Detect reactions

Hi, I'm trying to simply detect when any reaction has been added to any message. How can I do that? My end goal is to then check if it's in a certain channel before I store it temporarily, so if there's another way to do that that's also fine. I've tried using this code on Collectors just to get started understanding them from https://discordjs.guide/popular-topics/collectors.html#message-collectors but it seems like it needs to be in a command, which i'm not sure where in a command it would be since commands have a short life span and this is a more long (2 day) active thing.

// `m` is a message object that will be passed through the filter function
const collectorFilter = m => m.content.includes('discord');
const collector = interaction.channel.createMessageCollector({ filter: collectorFilter, time: 15_000 });

collector.on('collect', m => {
    console.log(`Collected ${m.content}`);
});

collector.on('end', collected => {
    console.log(`Collected ${collected.size} items`);
});

// `m` is a message object that will be passed through the filter function
const collectorFilter = m => m.content.includes('discord');
const collector = interaction.channel.createMessageCollector({ filter: collectorFilter, time: 15_000 });

collector.on('collect', m => {
    console.log(`Collected ${m.content}`);
});

collector.on('end', collected => {
    console.log(`Collected ${collected.size} items`);
});

Any help appreciated! 🙂

for reference I'm doing the same thing here, but this is to check for new messages instead of checking for new reactions:

client.on("messageCreate", async (msg) =>
{
        //Check if need to start listening to messages first as to not waste resources
    if (UpvoteContainer.ON == true)
    {
        let upvote_channel_ID = 0;
        //check if message is in a channel used.
        for (const x of UpvoteContainer.valid_channel_IDs)
        {
            if (x == msg.channelId)
            {
                upvote_channel_ID = x;
                break;
            }
        }
        //Only proceed is a valid channel is being used
        if (upvote_channel_ID != 0)
        {
            if (msg.author.tag != client.user.tag)
            {
                UpvoteContainer.msgID.push(msg.id);
                UpvoteContainer.msgAuthor.push(msg.author.displayName);
            }
        }
    }

client.on("messageCreate", async (msg) =>
{
        //Check if need to start listening to messages first as to not waste resources
    if (UpvoteContainer.ON == true)
    {
        let upvote_channel_ID = 0;
        //check if message is in a channel used.
        for (const x of UpvoteContainer.valid_channel_IDs)
        {
            if (x == msg.channelId)
            {
                upvote_channel_ID = x;
                break;
            }
        }
        //Only proceed is a valid channel is being used
        if (upvote_channel_ID != 0)
        {
            if (msg.author.tag != client.user.tag)
            {
                UpvoteContainer.msgID.push(msg.id);
                UpvoteContainer.msgAuthor.push(msg.author.displayName);
            }
        }
    }

I was hoping I could use client.on("messageReactionAdd" ) but apparently that only works with "cached" messages so if anyone also knows how to do that that'd be nice as I feel more confident with using client.on()
