brush and pan in VR

Hi All.

I am creating a simple interaction where the user uses a brush and pan to sweep up some rubbish. I say simple but i'm not quite getting the interaction to work. I have the pan and brush working ok using Oculus HandGrabInteractable and managed to fudge a bit of rubbish getting swept onto the pan. I really think it's very crude though and am looking for any tutorial that you (the masses!) may have seen online which may be of help to get this into a much slicker execution.

Many thanks for your time.
