Fire Tv/Cube play radio station

I want to play an online radio station remotely on my Fire Cube, which is connected to my AVR.

Fire Cube is already in Home Assistant via ADB but at the moment there is no app recognized.

How to make a script to start TuneIn and select a certain radio station?
Do I need:

  • service: media_player.select_source
  • service: media_player.play_media
    ?
