MusicKit compatibility with macOS

I'm trying to build a small toy MusicKit app on macOS Ventura (beta 4), and am running into something I think is probably an easy issue. I've started with the single-view application template, and have added a button, the target of which calls MusicKit methods:

@IBAction func buttonPushed(_ sender: Any) {

    Task {
      let status = await MusicAuthorization.request()
      switch status {
      case .authorized:
        print("auth")
      case .restricted:
        print("restricted")
      case .notDetermined:
        print("not determined")
      case .denied:
        print("denied")
      @unknown default:
        print("default")
      }
      print(MusicAuthorization.currentStatus)
    }
}

I have added the NSAppleMusicUsageDescription key to the application's Info.plist

However, I am always seeing that MusicAuthorization.request() returns denied with no prompt to the user for access. Thank you in advance.
