Accessing to the rendered image in RealityKit

Hello

I have developed an app to be able to record videos with ARKit and RealityKit. Right now, accessing to the frame from ARKit I'm able to get the image of the camera to record it.

The problem is that the 3D objects are being display in the RealityKit view so they aren't being recorded. I would need to know if there is a way to access to those picture frames somehow, due to having to record the video without the UI.

Thank you!
