"Show media playback controls" in Google maps.

Ever since Google maps dropped the deezer controls I've either had to split screen deezer/maps, flick between the 2 or pull the panel down from the top to gain access to the next/previous/play/pause buttons.

I maps there's an option to "show media playback controls" within settings whilst in navigation but it only allows Spotify. 

Is there going to be an option for Deezer? Screen shot showing both attached.
