My content supports hand tracking. However, when I wake up from sleep, the “Turn on controllers” window appears. Is there a way to prevent it from appearing?

[How to assign function to the headset button ?]

I would like to assign function (eg.  open menu, stop game and etc.) to the headset button. 
Do you provide an API for that? Please let me know if you have any sample code.

[How to recenter?]

I see. Thank you for your support !!

[How to recenter?]

I followed the tutorial to set up the project and it worked fine.

I would like to add a function to reset the front (recenter). Do you provide an API for that? Please let me know if you have any sample code.

I tried the code below but it didn't work.

InputDevices.GetDeviceAtXRNode(XRNode.Head).subsystem.TryRecenter();
