Ionic MusicKitJS in App no authentification possible

Question

I tried to authorize a user in my App with the normal AppleMusic login popup.

music.authorize().then(()=>{
  //do something
}

In the Webversion there poped up the Apple login form. But when I compile the App and run it on a device i think the popup is blocked or something.

How can I allow the Apple Music authorisation in my native app?
