Can I use Deezer in Apple Home Automation?

Unfortunately it seems that it’s still not possible to use Deezer in Apple scenes or automation. My son normally says Siri goodnight and than the lights go out, curtains close and music starts to play. Unfortunately I can only choose Apple Music for this and not Spotify or Deezer. Does anyone know how to solve this problem?
