How to Upload Music Onto App?

I am trying to figure out how to make a music player that uploads music to my app. However, all the tutorials I found were on Thunkable Classic. Can someone please help me figure this out?

Have you seen this page?

If that doesn’t answer your question, provide more details about what you’re wanting to do (e.g. what would a user do, what would happen when they do that, what would happen in the app behind the scenes, etc.).

how to you make it so the user of the app can upload the music and play it, instead of having pre-uploaded files

I don’t think that’s possible.
