ARFoundation uses RGB camera instead of TrueDepth on iPhone X - 13

Hello, I am trying to get ARFoundation running with an ARFaceManager using the TrueDepth camera on an iPhone X or iPhone 13.

However, it seems to be using the RGB camera instead! I can cover up the TrueDepth camera and the RGB is still tracking my face, and it does not work well in the dark unlike TrueDepth. I would like to use TrueDepth for more accurate tracking.

Is there an option somewhere for ARFoundation to prefer TrueDepth camera tracking instead of the RGB camera? Thank you!

ARFoundation is backed by Apple’s ARKit face tracking.
