This was also a big one for me. The best workaround I've come up with so far is to set up a global hotkey to toggle microphone mute in KDE, and then set my Discord (etc.) to have very sensitive "voice activation" settings. Essentially I've replaced push to talk with "push to toggle mute". Not the same thing, but I got used to it pretty quick.

Having read some of the threads on the freedesktop wayland gitlab repo about push to talk, I'm not confident push to talk or any other system for applications to register a global hotkey is something they'll deliver any time soon (if ever).

Have a look at https://github.com/waycrate/swhkd, last time I tried to use it it was still quite janky, but it might have improved since.
