AR with oculus quest 2

Hello

I'm trying to make a simple AR app with the oculus quest 2, something similar to the Passthrough of the home, but I don't know how to capture the cameras to show reality on the scene.

Example:

The Unreal Engine AR examples don't work, and I can't find any documentation about this.

Can someone help me indicating me if it is not possible to do this or what I have to do to be able to do this project?

Thanks in advance
