KDE Global Shortcuts & Discord Push-to-Talk Conflict

I am on NixOS Unstable and Discord 1.0.168. I have used keybinds on my B and Z keys in Discord to push-to-mute myself so I can speak ingame without “double speaking”. When those custom keybinds are enabled, I cannot use my B or Z keys in any other window. Under “Legacy X11 App Support” I have enabled “Listening for keystrokes:” to “Always allowed”. This originally allowed my B and Z keys to not get obstructed by Discord. Anyone have any other workarounds? I want to make sure I can speak ingame ...
