ApplicationMusicPlayer plays music while app is in background

Taking the reference I expected the ApplicationMusicPlayer in my app to pause as soon as I go to the background. It doesn't happen in my app (I don't have any background modes configured for my app). Also - the playback status and queue is not visible in the Apple Music app, butits visible and controllable with the Apple Music Widgets.

Is this actually a bug or I'm doing something obviously wrong? Or everything works as expected and I just don't understand/overinterpret something?

Code:

@main
struct SoundMarkerApp: App {
  @Environment(\.scenePhase) var scenePhase
   
  var body: some Scene {
    DocumentGroup(newDocument: SongDocument()) { file in
      Text("V")
        .onAppear {
          Task {
            do {
              let player = ApplicationMusicPlayer.shared
               
              let searchRequest = MusicCatalogResourceRequest<Song>(
                matching: \.id,
                equalTo: MusicItemID("254945856")
              )
              let searchResponse = try await searchRequest.response()
              player.queue = [searchResponse.items.first!]
              try await player.prepareToPlay()
              try await player.play()
            }
          }
        }
        .onChange(of: scenePhase) { newValue in
          print(newValue)
        }
    }
  }
}
