itunes – Is it possible to create an extension that appears in the Music app’s sharing menu?

macOS of course has an Extensions control panel in the System Preferences,

Extensions control panel in System Preferences

so it is clearly possible to make sharing extensions that appear somewhere. But not all of the sharing options that appear in Music are in the Extensions control panel:

Music sharing options

and those that do are very generic, so it’s not clear to me whether I can extend the sharing options in Music or not. Additionally, most of the extensions in the “Share Menu” category are not appearing in’s “Sharing” menu.

Is it possible to write an extension that will appear in the Sharing menu in the Apple Music app?
