Hi there!
I know that this is not related to MusicKit but Apple Music API, but I am curious to know where to find the activities to use this identifier?
Get a Catalog Activity endpoint:
https://api.music.apple.com/v1/catalog/{storefront}/activities/{id}
If I use the example ID given on the page, I get "Resource Not Found"
error.
So, where do I get the activities ID?
