Is it possible to get distance based on depth map?

Im trying to set up some collision using the experimental hand tracking. I was wondering if its possible to get or infer distance of a screen point position based on the depth map so I can try to roughly place a collider.

The AR depth manager can infer the distance with the DepthManager.DepthBufferProcessor.GetWorldPosition() function.
Here’s how i use it in one of my projects:

Your a life saver thank you!
