remote control Deezer instans from phone or other device

I i have deezer open in my browser on my pc or on my pc connected to my audio system and i want to select the songs i would like to play on my other running instance. There is just the notification that someone else is listening. And playback stops. Just let me remotely control my other instance and, if possible, also the volume fader. (tbh just do it like Spotify is doing it; it works really well there.)

I found this here 

But this is not doing it for me. I can not control the desktop client, and mostly I'm using the browser, and I also cannot remotely control the app there.
