Keybinds on Linux with remapped keys

I have mute mic set to ctrl+m, and I have it set through xkbmap (the Xorg utility) that the caps lock key is now my ctrl key. However, when I press caps(ctrl)+m, nothing happens, and I have to use the actual ctrl key for the keybind to activate. This isn't a problem in any other app that I've found, so it appears to me that it's specifically the way Discord's Linux client reads key input.

Is there a way to fix this client side? Is Discord willing to change the way it reads key input for shortcut keys? Or is nobody else concerned by this and I should just bite the bullet and buy a keyboard that actually has the ctrl key in the caps lock place?
