Trying to fix sprite picking when covering mesh

I have not finished it yet (had just dealt with the pointerDown event, not including pointerUp pointerMover or others, and there must be other related effects I have to handle).

Can you please tell me how to make sprites unpickable when they are obscured by the mesh? [20230816_17255320238161727281] Sprites Examples | Babylon.js Playground (babylonjs.com)
