This guy was able to modify the Windows version of Chiaki so that when using a non-Playstation controller, the Select button acts as Trackpad click by default. I tested this on my Windows machine and it works perfectly with my 8BitDo Ultimate controller.

Is it possible to replicate this on Chiaki4Deck as well? I understand we can map buttons with Steam but whenever I do that it only really works handheld, when I have the Deck docked using that same 8BitDo controller, no matter how I map it in Steam, pressing the select button still activates the Share function on my Playstation. SOMETIMES it will also act as a trackpad click, but even when it does it will still always take a screenshot too.
