Left hand controls don't work on SteamVR Input 2.0

## Description
Quick bug report, it's in the title: the right hand controls work, but left hand doesn't. Can you fix this on quest? Can you also add options to configure the controls for hand tracking hand controls, like disabling buttons or changing the gesture you use? Perhaps also gestures for joystick directions. I like to play games with hand tracking that don't support it like rec room. Thank you!
