ARKit rgbimage frame acces

Hi, Im Unity Developer and using Apple ARkit XR Plugin package for my project development.

I want to access ARkit rgbimage frame and convert to texture2D in my project.

It seems that ARkit overrides camera authorization both back and front, so grabbing wecamtexture using another API(e.g. unitywebcamtexture class) does not allowed.

Also ARKit does not provide official root to directly get frame from AR camera.

Is ther anyone resolved this issue?

Thank you.
