Voice chat companion - see it in tablet or smartphone

Problem:

Overlay don't work with my game (Vulkan)
or
Overlay makes UI too cluttered.

Suggestion:

When logged in both desktop and mobile clients, to be able to see in mobile (i.e. Smartphone) a black screen with only the voice chat participants.

For screensaving' sake with faded colors or show up the participant only on voice activity.

Misc:

I've managed to work a similar solution by using my android device as a second monitor, then opening a browser with the StreamKit Overlay solution.

But it would be much more less complicated and beneficial to use the already installed Discord App.
