Please allow PC build w/ face, eye tracking for PCVR in Unity/Unreal and not rely on OpenXRtoolkit

I have noticed the face / eye / hand tracking for the Quest pro is limited to only android builds when building with Unity or Unreal, and we have to use third party workaround hacks like OpenXRtoolkit to get it working. Meta can you please give proper PCVR support in the Movement SDK and Unreal so we can build for PC using these features?

In addition it would be nice to get PCVR MR support. I feel this will create a trickle down effect, some of us are trying to push the boundaries of PCVR but can't since it doesn't work natively, only for standalone builds.
