Feature Request: Xbox Elite 2 Controller support

[ffpyt]

Hello there,

I just got a new Xbox Elite Series 2 controller and connected it via Bluetooth to my Bazzite PC. It is listed in Controller Tools but without showing the battery percentage.

I am a bit surprised as I would have thought it similar if not same as the regular Xbox controllers.

I'd appreciate if it could be fully supported.

Controller Tools v2.0.2

Thanks a lot for the great plugin!
