[Request] Allow option to use M4/M5 to swipe between fullscreen app pages

[NichCodes]

Thanks for working on this app! I've gotta use a standard mouse with M4/M5 keys on my Mac desktop nowadays, and this makes it a lot more useful.

I wanted to suggest an extra option, if possible: Could we have it so the M4/M5 keys emulate a swipe left/right between different fullscreen applications in the same desktop instead? I tried rebinding the three-finger swipe gesture in Preferences, but that didn't change anything.

The default keybind for doing this is Ctrl + Left/Right Arrow to slide left/right. I know the Logitech MX 3 does it, but I don't know how feasible it'd be here.
