Linux game controller keymapping with dead zones

So I dove into using a Nintendo Switch controller as a keyboard replacement due to ergonomic issues. I’m using AntiMicroX to map the buttons to keypresses. It seems pretty promising, but it turns out you need a surprisingly large number of buttons to be able to even mostly ditch the keyboard.

The biggest problem I have now is that I can’t really use the thumb stick for input, because it’s too sensitive. I need to find a way to define a dead zone for it. Does anyone have a solution for this?

Should be under one of the stick button

Thanks… I didn’t realize there might be more settings than just the keybindings behind those buttons.
