Most wayland compositors do include xwayland, but that doesn’t mean that applications will automatically use it. Applications that can run om Wayland will default to doing so. You need to explicitly tell them to do otherwise.
As for how, I’m pretty sure you just need to set an environment variable, but you will need to look up which one.
The link you posted https://github.com/leia-uwu/obs-wayland-hotkeys was most helpful because it showed a screen shot that shows system settings. I was not aware that was where I needed to go to set the hotkeys. TY
