Question about enabling filtering of items

Hello, I was curious if anyone had any idea on how to assign data to visual objects in .Net Maui? I have a list of trading cards that I am putting the image of into a grid with a couple other elements and then want to be able to set the visibility of the image and other elements based on a set of filters created using buttons or checkboxes. The main issue I am having is I can't figure out how to set the the properties of the card to be filtered. I don't know how good of an explaination of what I am asking that was so if anyone wants more info about what I am looking for just ask.

unable to parse Json data pulled from API as a list of strings

I am trying to take some data from an API called Scryfall API and assign it to a List variable. I am very new to this and have as of yet been unsuccessful in saving the URLs to the images in the API as a list of strings that I am going to use later. If anyone has any ideas I really could use the help. The main line of code I am using is:

List<string> imageUrls = jsonResponse["data"].Select(item => item["png"].ToString()).ToList();

List<string> imageUrls = jsonResponse["data"].Select(item => item["png"].ToString()).ToList();

Here is the rest of my retrieval code:

using Newtonsoft.Json.Linq;

namespace MBT.API
{
    public class APIHelper
    {

        // Limit the number of requests in a time period
        private readonly int MaxRequestsPerSecond = 15;
        private readonly TimeSpan RequestInterval = TimeSpan.FromSeconds(1);
        private DateTime lastRequestTime = DateTime.MinValue;
        private int requestCount = 0;

        private static HttpClient apiClient = new()
        {
            
            BaseAddress = new Uri("https://api.scryfall.com/cards/search?q=type%3Aland+-t%3Acreature+-t%3Aartifact+-t%3Aenchantment+-t%3Aplaneswalker+-t%3Asorcery+-t%3Ainstant"),

        };

        public async Task<List<string>> GetLandImages()
        {

            var url = "https://api.scryfall.com/cards/search?q=type%3Aland+-t%3Acreature+-t%3Aartifact+-t%3Aenchantment+-t%3Aplaneswalker+-t%3Asorcery+-t%3Ainstant";
            var response = await apiClient.GetAsync(url);
            bool requestCountStatus = CanMakeRequest();

            using (apiClient = new HttpClient(new HttpClientHandler
            {

                SslProtocols = System.Security.Authentication.SslProtocols.Tls12 | System.Security.Authentication.SslProtocols.Tls13

            }))
            {  

                if (response.IsSuccessStatusCode && requestCountStatus)
                {

                    string responseBody = await response.Content.ReadAsStringAsync();
                    JObject jsonResponse = JObject.Parse(responseBody);
                    
                    if(jsonResponse["data"] != null && jsonResponse["data"].HasValues)
                    {

                        List<string> imageUrls = jsonResponse["data"].Select(item => item["png"].ToString()).ToList(); //Broken. Need to fix.
                        return imageUrls;

                    }

                    return new List<string>();

                }

                return new List<string>();

            }
        }

        bool CanMakeRequest()
        {
            DateTime now = DateTime.Now;

            if (now - lastRequestTime > RequestInterval)
            {
                lastRequestTime = now;
                requestCount = 0;
            }

            if (requestCount < MaxRequestsPerSecond)
            {
                requestCount++;
                return true;
            }

            return false;
        }
    }
}

using Newtonsoft.Json.Linq;

namespace MBT.API

    public class APIHelper
    {

        // Limit the number of requests in a time period

        private static HttpClient apiClient = new()
        {
            
            BaseAddress = new Uri("https://api.scryfall.com/cards/search?q=type%3Aland+-t%3Acreature+-t%3Aartifact+-t%3Aenchantment+-t%3Aplaneswalker+-t%3Asorcery+-t%3Ainstant"),

        };

        public async Task<List<string>> GetLandImages()
        {

            var url = "https://api.scryfall.com/cards/search?q=type%3Aland+-t%3Acreature+-t%3Aartifact+-t%3Aenchantment+-t%3Aplaneswalker+-t%3Asorcery+-t%3Ainstant";

            }))
            {  

                if (response.IsSuccessStatusCode && requestCountStatus)
                {

                    string responseBody = await response.Content.ReadAsStringAsync();
                    JObject jsonResponse = JObject.Parse(responseBody);
                    
                    if(jsonResponse["data"] != null && jsonResponse["data"].HasValues)
                    {

                        List<string> imageUrls = jsonResponse["data"].Select(item => item["png"].ToString()).ToList(); //Broken. Need to fix.
                        return imageUrls;

                    }

                    return new List<string>();

                }

                return new List<string>();

            }
        }

        bool CanMakeRequest()
        {
            DateTime now = DateTime.Now;

            if (now - lastRequestTime > RequestInterval)
            {
                lastRequestTime = now;
                requestCount = 0;
            }

            if (requestCount < MaxRequestsPerSecond)
            {
                requestCount++;
                return true;
            }

            return false;
        }
    }
}

and this is the properties for the json retrieval itself:

using Newtonsoft.Json;

namespace MBT.API
{

    public partial class ScryfallApiResponse
    {

        [JsonProperty("data")]
        public List<CardFace> Cards { get; set; }
    
    }

    public partial class CardFace
    {
        [JsonProperty("image_uris")]
        public ImageUris ImageUrls { get; set; }
    }

    public partial class ImageUris
    {
 
        [JsonProperty("png")]
        public Uri Png { get; set; }

    }
}

using Newtonsoft.Json;

namespace MBT.API
{

    public partial class ScryfallApiResponse
    {

        [JsonProperty("data")]
        public List<CardFace> Cards { get; set; }
    
    }

    public partial class CardFace
    {
        [JsonProperty("image_uris")]
        public ImageUris ImageUrls { get; set; }
    }

    public partial class ImageUris
    {
 
        [JsonProperty("png")]
        public Uri Png { get; set; }

    }
}

Thank you for any help in advance.
