Does ARKit report hand tracking data from facedown camera?

Hi, all, so we know that Vision Pro can track hand using facedown camera. And I'm wondering does ARKit also report hand tracking data from facedown camera?

From my testing it looks like ARKit only reports hand tracking data from front view cameras, but not facedown cameras. Is this expected? If so, I assume facedown camera hand tracking data is only available to Vision OS but not to other apps through ARKit?

This one is not exactly what you want, but I think you can get some idea from this open source.
