Just in case it helps:

My Discord keybinds were having a struggle when I used 3rd party apps like armcord and vesktop. The actual Discord bin program is doing global keybinds correctly for my toggle mute microphone on my keyboard.

Can confirm, I helped a friend put Fedora on their old laptop to give it life again. Even though I wrote them instructions, once it came time for the terminal stuff, they video called me, lol. They love using that laptop now, though! They were in their early 20s for reference.
