Pinch gesture from hand tracking

Is there a robust way to track a pinch (with handeness) from hand tracking? I know we can get an overall pinch from spatialpointer data but I need a hand version of it for physical interactions.

I tried simple distance from tip to thumb and its really unreliable and doesn’t consistently report “pinch” state, probably because the hand tracking is not that reliable to begin with.

The Mixed Reality scene from the package samples shows an example on how to do this.

The reliability of tracked joints is more on the platform side and something you can provide feedback to Apple on the via the feedback assistant.
