How can we get the video stream in Oculus quest2 in Unity3D?

Hi! I am a VR game developer. How can we get the video stream in Oculus quest2 in Unity3D?

I am using unity3d.

- I want to export the video capture by the four cameras.

- I want to get a video of the surrounding environment shown in the display.

Can I do this using unity3D pkgs?

Are these functions contained in the Oculus lib？
