Because not all controllers have a touchpad, in the R90 solution, the touchpad uses button + joystick to simulate some touchpad gestures of the ps controller.
And because the joystick is used, if the joystick is occupied during this process, the simulation logic cannot proceed.
If you find that the touchpad fails to press down without moving the joystick, you can check whether the joystick is in a drifting state.
