Question How to see the inside part of a mesh object (URP)

Hi,

I'm programing some stuff for AR, and I would like to do this : The player has a tool, let's say a glass plane, and when he puts the plane on a 3D mesh object, he can see inside (everything on the object thats between the tool and the player's eyes is masked).

It's like i cut through the object, but as i move the tool away the parts that were masked reapears.

Thing is, I've got no idea how to do that ^^" (I'm working with URP also). I guess this will be a matter of shaders and stuff...

Can anyone help ?

Thanks
