Recording mixed reality (passthough) PCVR apps (post v47)

Is it possible to record mixed reality (passthrough) PCVR apps now that v47 has been (gradually) released? The release notes specify that users can now record MR/passthrough "on Meta Quest Pro devices", but it isn't clear whether this functionality extends to PCVR with a tethered Quest Pro running a MR app.

Things we have tried post v47:
Native Quest Pro recording / on device (passthrough appears as black background)
Sidequest streaming (PC steam goes black once our unity application launches)

----

v47 release notes for mixed reality capture ie. capturing passthrough instead of a black screen on Quest Pro

Mixed Reality Capture (Meta Quest Pro only)

Share the magic of mixed reality with friends and family. On Meta Quest Pro devices, you'll now be able to capture photos and videos while using mixed reality in Passthrough.
