HTML5 Audio: Native Audio Controls not showing up on Android

Hello,

I’m using HTML5 Audio in my Capacitor App to play music. On iOS, the native Audio controls are showing up, like you see in this screenshot.
Sadly, it doesn’t show up on Android. Surprisingly, it shows up if I open my Ionic/Capacitor App in the browser and press play. See the Web-App: https://audio-player-sigma.vercel.app

This is my Code:

const player = new Audio();

player.src = 'https://file-examples-com.github.io/uploads/2017/11/file_example_MP3_2MG.mp3';

player.onplay = () => {
  if ('mediaSession' in navigator) {
    navigator.mediaSession.metadata = new MediaMetadata({
      title: 'Lorem Ipsum',
      artist: 'Lorem Ipsum',
      album: 'Lorem Ipsum',
      artwork: [
        { src: 'https://dummyimage.com/96x96', sizes: '96x96', type: 'image/png' },
        { src: 'https://dummyimage.com/128x128', sizes: '128x128', type: 'image/png' },
        { src: 'https://dummyimage.com/192x192', sizes: '192x192', type: 'image/png' },
        { src: 'https://dummyimage.com/256x256', sizes: '256x256', type: 'image/png' },
        { src: 'https://dummyimage.com/384x384', sizes: '384x384', type: 'image/png' },
        { src: 'https://dummyimage.com/512x512', sizes: '512x512', type: 'image/png' },
      ]
    });
    console.log('init mediaSession metadata');
  } else {
    console.log('mediaSession not available');
  }
};

So it works in the system browser, but not in .apk built by capacitor. On the iOS App aren’t any problems. Everything works fine.

Any ideas how to get it working on the android capacitor project?
Thanks!
