Is your feature request related to a problem? Please describe.

As stated in this Arch Wiki Page the Steam Deck's (OLED) built in controller's Trackpads operate normally until any app hooks into it at which point it'll switch to emulating a generic XInput controller, disabling the Trackpads (and any PC utility functionality) until all hooked apps are exited.

Describe the solution you'd like

Just add the Trackpads in the software alongside the already existing Gyroscope & Accelerometer.

Describe alternatives you've considered

There are none, AntiMicroX is the best.

Additional context

AntiMicroX come bundled with the Dr460nized Gaming Edition of Garuda Linux and because of this software it is the only Linux distro I've not only made any true headway in in setting up and using an alternate open OS on my Steam Deck OLED, it's become my most used & successful instance of Linux ever (I still game using Windows 7 daily) in attempting to migrate to Linux from Windows.

Doability of this depends on this whether SDL implemented support for them.

In SDL3 SDL_GamepadTouchpadEvent was introduced https://wiki.libsdl.org/SDL3/SDL_GamepadTouchpadEvent

So for now this feature is blocked by #1106
