MusicKit: URL to a song in user's Music Library in macOS?

I am looking for a way to get a URL to a MusicItemID/Song that is in the users music library after finding the song using MusicKit search. I would like the linked song to open the system music player.

MusicCatalogSearchRequest has a link to the song, but MusicLibrarySearchRequest songs don't include a url.

var searchRequest = MusicLibrarySearchRequest(term: searchTerm, types: [Song.self])

let s = try await searchRequest.response()

resultSongURL = s.songs[0].song.url  **alas, empty url**

macOS also lacks access to SystemMusicPlayer when not using Catalyst.

Thanks!
