Reading keys from Remote Catalog at runtime

Example: I launch a mobile app that is a game that lets the user spawn colored balls. The app is launched only with the colored balls: red, green, blue.

A week later, we create colored balls: purple, pink, black. We generate the Addressables for them and upload them to our remote server.

I understand that the whole point of addressables, is that at runtime the launched app could download the newly created 'purple, pink, black' balls using for example: Addressables.LoadAssetAsync("purple");

But what I can't understand, is HOW the launched app knows that there are now key names / assets of "purple, pink, black" available for use / download?

I've been searching through the Addressables API and can't seem to find how I can access the available Keys from the remote catalog.... I feel like I'm overlooking something very simple, but am pulling my hair out.

Thanks

 

Searching the forums more, I found this post: https://forum.unity.com/threads/whats-the-api-to-get-addressables-catalog.578197/#post-3882424

This is closer to what I'm looking for, but still isn't what I want. This lists each individual file....that are packed into my addressables (I think?).

How can I get the actual `Asset Address` string names?

 

I finally was able to make some progress. This is not exactly what I was hoping for, but I was able to load the Keys for all the Addressables that belong to a given Label:

Code (CSharp):

1. public void Start()
2. {
3.     Addressables.LoadResourceLocationsAsync("My_Addressables_Label").Completed += OnLoadAddressableKeys;
4. }
5.  
6. private void OnLoadAddressableKeys(AsyncOperationHandle<IList<IResourceLocation>> obj)
7. {
8.     foreach (var k in obj.Result)
9.     {
10.         Debug.Log(k.PrimaryKey);
11.     }
12. }
13.
