Play music in background while on other Inputs on Android TV

I love Deezer to death especially when it comes to music recommendations on the flow 

basically Spotify has the ability to cast to Android TV and play in the background  regardless of what TV input you're on so if i wanna listen to music while playing my Nintendo Switch or playstation i can with Spotify. However with Deezer if i attempt to do the same it will exist out of the input go to the home screen and play in the deezer app if i try to change inputs the music stops. So if you could make this a feature or even something like getting on the PS5 this would be the perfect music service
