MusicKit - Not showing as a capability in Xcode

A bit of a novice to app development here but I have a paid developer account, I have registered the identifier for MusicKit on the developer website (using the bundle identifier I've selected in Xcode) but the option to add MusicKit as a capability is not available in Xcode?

I've manually updated the certificates, closed the app and reopened it, started a new project and tried with a different demo project?

Apologies if I am missing something obvious but could someone help me get this capability added?
