RPC VS Discover

It's a custom rich presence, take a look at this: https://github.com/discordjs/RPC

I run this using the 'npm run' in a git bash window. haven't quite learned how to do that with visual studio yet.  This is the library I've been using, discordjs rpc  ​here​​​

This is what I used, although there are probably more friendlier/easier ways to setup Rich Presence.

It still can be used if you use an wrapper that uses the ipc channel like this one https://github.com/discordjs/RPC

Discord overlay doesn't exist in linux. I'm using Discover as a workaround.

If you know python you could maybe start by looking at how discover handles everything by reading its source code

There are applications like Discover for Discord. It is capable to render above everything else, even fullscreen games without taking any resources.

1) If you use Discord, install it and the Discover overlay. With the Deck's excellent output cancelling, you can comfortably chat while you play.

Python GTK Linux Example that works on Steam Deck: https://github.com/trigg/Discover

Discover Overlay: This lets you have an overlay for Discord, since Discord on Linux still has no overlay support of its own. It's a little janky, but being able to see who's talking and read what the people in text chat are saying is just an important part of being social online. I love being able to both play video games and hang out with friends simultaneously, so this is just about mandatory for me.
