Input System can not detect LapTop TouchPad Input

Hello guys:
I’m currently working on migrating my mobile game to PC, and I’m using Unity 2021.3.16f1, with InputSystem 1.4.4, I’m not quite sure if this is a bug or if I set something wrong.
What I’m trying to do is add the Left Button[Mouse] to my actions in the input system to allow PC players can also play the game as mobile players.
But after I added the Left Button[Mouse] to my actions manually, it wouldn’t trigger anything in the game, however, I can still use my touchpad to interact with UI buttons in-game. Also, “Listen” can only find keys on my keyboard, but nothing from my touchpad.

I think I found something, to make the Mouse work, you need to enable your mouse device in the Input Debugger manually every time you enter play mode.
