Describe the bug

When you Gaze and say "Select" on a HoloLens 2, the MRTK input system should fire the appropriate events for the "select" action. This no longer works like it did for the Legacy XR. Other keywords work just fine.

To reproduce

Steps to reproduce the behavior:

The easiest way to see the problem is with the EyeTrackingDemo example

1. Install the OpenXR Plugin
2. Import the EyeTracking demo
3. Deploy to the HoloLens 2
4. In the TargetSelection scene, say "select" while looking at a gem, the speech confirmation tooltip appears, but the gem does not explode. Saying "explode" does explode the gem.
5. Gaze at a different scene in the Scene Menu and say "select". It's no longer possible to change scenes with the "select command".

Expected behavior

Saying "Select" should fire the appropriate events to cause a "select" action.

Screenshots

Unfortunately, the "select" tooltip isn't captured when I try to take a screenshot.
