Adding Deezer as podcast service to Google Assistent

I really love hearing my podcasts on Deezer while driving my car using Android Auto. However, I always need to start them by selecting on the screen as they don’t start with voice command (which does work for music).

I would think this is due to Deezer is not selected as my podcast service in Google Assistant. I can only select Youtube or Spotify there (screenshot - german).

Would be great if you can make Deezer availble there.

Thanks!
