Add webcam face texture to a face geometry with ARFoundation

Hi,
Can you help me to solve this? I have created a face geometry in ARWorld (using ARFoundation) with no texture. Now I want to add the webcam face texture to the shape, it will look like my real face talking in realtime and with a 3D shape:

Someone there???

The idea is to create something like this:


Looks simple, after created the mesh add the webcam texture in live.
