Is Meta Quest Pro Passthrough not supported in Unreal Engine remote play in editor?

I'm trying to view a project in Unreal Engine 5 as a remote vr preview using MetaQuest Pro passthrough.
Reality and VR are not mixed and displayed at the same time. Tap the right side of the headset twice to see reality, tap twice again to see vr. I can't mix the two at once.
