How to access XRInputSource/XRSourceInputArray of InputComponent?

Q&A
#1

Does the WL.InputComponent give access to the XRSourceInputArray? To read buttons states on a controller?
Is it “WL.xrSession.inputSources”?

#2

If you have a input component, you can inputComp.xrInputSource (https://wonderlandengine.com/jsapi/inputcomponent/#xrinputsource)
That will return the input source for the right/left hand, depending on the input component’s type

#3

for something fast, u can do
WL.xrSession.inputSources[0].gamepad.buttons[index].pressed
tho u can’t know if it is left or right
