Physics Raycast with Oculus Quest Hand Tracking

Anyone have any luck creating the typical curved teleport line from a raycast but with just hand tracking on the Quest?

I'm still very much a novice with Unity and C#, though from some example code I managed to get a visible raycast, but the origin transform.position I'm using for the line on the OVRHand is coming from the wrist. I'd like to have it come from the tip of one of the finger bones, or from the middle of a pinch gesture, but I'm not sure how I'd go about it.

I thought maybe OVRHand.HandFinger.Index.transform.position might work but it doesn't.
