Meta Aim Hand OpenXR feature

Unity OpenXR provides support for the Meta Hand Tracking Aim extension specified by Khronos. For this extension to work, you must also enable the Hand Tracking feature.

For this extension to be available, you must install the OpenXR package.

For this extension to work when deployed to a Meta Quest device, your OpenXR package must be set to at least version 1.6.0.

You can either use the Unity Input System drop-down menus in the editing UI for Input Action Assets, or directly enter bindings like below.
