Library Playlists Sharing

Hello all,


We've discovered that sharing a playlist from user's library in the Apple Music iOS App generates a parameter globalId that allows matching with the real catalog playlist.

Is this globalId parameter documented somewhere ? We couldn't find any information in the official API:


https://developer.apple.com/documentation/applemusicapi/get_a_library_playlist


Is there a way to trigger its creation from a 3rd party app using the MusicKit?


Thank you very much for your help,

Jean
