Name for the keybind of the AP disconnect switch on the yoke?

Hey, im trying to bind the AP disconnect switch on the yoke to my joystick, so I can easily disconnect the AP by pressing that button twice instead of trying to click it twice in the sim with my mouse. Problem is I just can't find the right binding, can anyone please tell me what the name of that binding is or if it even exists?
