❔ async await nooob trying to do the simplest of simple await for a string to be returned?

This is my Client code:

        public static string GetName(NamingSystemType type, long id)
        {
            if (names.TryGetValue(type, out Dictionary<long, string> dict))
            {
                if (dict.TryGetValue(id, out string name)) return name;
                else
                {
                    CommsManager.Instance.CMD_RequestName(id);
                    return "";
                }
            }
            else return "";
        }
        public static void AddName(NamingSystemType type, long id, string addingName)
        {
            if (!names.TryGetValue(type, out Dictionary<long, string> dict))
            {
                names.Add(type, dict = new Dictionary<long, string>());
            }
            if (dict.TryGetValue(id, out string name))
            {
                return;
            }
            else dict.Add(id, addingName);
        }

        public static string GetName(NamingSystemType type, long id)
        {
            if (names.TryGetValue(type, out Dictionary<long, string> dict))
            {
                if (dict.TryGetValue(id, out string name)) return name;
                else
                {
                    CommsManager.Instance.CMD_RequestName(id);
                    return "";
                }
            }
            else return "";
        }
        public static void AddName(NamingSystemType type, long id, string addingName)
        {
            if (!names.TryGetValue(type, out Dictionary<long, string> dict))
            {
                names.Add(type, dict = new Dictionary<long, string>());
            }
            if (dict.TryGetValue(id, out string name))
            {
                return;
            }
            else dict.Add(id, addingName);
        }

Await server to give name to client after request: This is client code aswell, which is called by ChatSystem for example:

        internal static Task<string> GetNameAsync(long id)
        {
            // while(waitingForNameToBeAdded)??
How do I wait for server to addName as seen above?
        }

        internal static Task<string> GetNameAsync(long id)
        {
            // while(waitingForNameToBeAdded)??
How do I wait for server to addName as seen above?
        }

❔ EntityFramework - How do I figure out what ORM expects?

#region Assembly AgeOfSailOnline_DB, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null
// AgeOfSailOnline_DB.dll
#endregion

#nullable enable

using System;
using System.ComponentModel.DataAnnotations;
using System.ComponentModel.DataAnnotations.Schema;

namespace AgeOfSailOnline_DB.Entities
{
    [Table("accounts", Schema = "main")]
    public class AccountEntity
    {
        public AccountEntity();

        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        [Key]
        public long AccountID { get; }
        public string Email { get; set; }
        public string Salt { get; set; }
        public string Verifier { get; set; }
        public DateTime Created_At { get; set; }
        public bool Banned { get; set; }
        public bool IsGameMaster { get; set; }
    }
}

#region Assembly AgeOfSailOnline_DB, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null

using System;

    public class AccountEntity
    {
        public AccountEntity();

        [DatabaseGenerated(DatabaseGeneratedOption.Identity)]
        [Key]
        public long AccountID { get; }

        public DateTime Created_At { get; set; }
        public bool Banned { get; set; }
        public bool IsGameMaster { get; set; }
    }
}

I get an error:

No account.account_id found.

So I changed my DB table from accountid to account_id. Now it works as expected. but how do i know in advance what the Database expects? This is EF Core related according to PostgreSQL devs (my DB provider). For example right now EF Core also expects is_game_master but i want it to just be gm Thanks for your time!

❔ UniTask / Unity - await/async connoisseurs wanted. Need help understanding

    public void TryRegister()
    {
        TryRegisterAsync().Forget(); // UI Register Button - Fire & Forget Method, 
    }
    public async UniTaskVoid TryRegisterAsync()
    {
        PlayerSelectionData[] psd = await tryRegisterAsync();
        
        UI_PlayerSelection.Instance.Init(psd);
        gameObject.SetActive(false);
    }
    private async UniTask<PlayerSelectionData[]> tryRegisterAsync()
    {
        var email = _emailInput.text;
        var pass = _passwordInput.text;

        PlayerSelectionData[] psd = await CommsManager.Instance.CMD_TryRegisterAsync(email, pass);

        return psd;
    }

    public void TryRegister()
    {
        TryRegisterAsync().Forget(); // UI Register Button - Fire & Forget Method, 
    }
    public async UniTaskVoid TryRegisterAsync()
    {
        PlayerSelectionData[] psd = await tryRegisterAsync();
        
        UI_PlayerSelection.Instance.Init(psd);
        gameObject.SetActive(false);
    }
    private async UniTask<PlayerSelectionData[]> tryRegisterAsync()
    {
        var email = _emailInput.text;
        var pass = _passwordInput.text;

        PlayerSelectionData[] psd = await CommsManager.Instance.CMD_TryRegisterAsync(email, pass);

        return psd;
    }

Is this correct? I want to wait for Server (via CommsManager) to reply with PlayerSelectionData[], after receiving that, I want to call UI_PlayerSelection.Instance.Init(psd); BTW, UniTask is pretty much the same as C# Tasks, just a different keyword for example async void == async UniTaskVoid. CommsManager (method just for testing):

    public async UniTask<PlayerSelectionData[]> CMD_TryRegisterAsync(string email, string pass)
    {
        await UniTask.Delay(1000);

        var psd1 = new PlayerSelectionData("Player_1", 3);
        var psd2 = new PlayerSelectionData("Player_2", 10);
        return new PlayerSelectionData[] { psd1, psd2 };
    }

    public async UniTask<PlayerSelectionData[]> CMD_TryRegisterAsync(string email, string pass)
    {
        await UniTask.Delay(1000);

        var psd1 = new PlayerSelectionData("Player_1", 3);
        var psd2 = new PlayerSelectionData("Player_2", 10);
        return new PlayerSelectionData[] { psd1, psd2 };
    }

This seems to work... But I heard its incorrect, see replies below. Thanks
