Hi, probably not useful but thought I’d mention just in case - have you tried using the double tap feature on Quest 2 to briefly activate the pass through camera? You can jot down your notes then double tap to re-enter VR.
As I said, probably not ideal due to the loss of immersion, and the camera quality isn’t the best, but the feature can be quite handy at times.
I occasionally use mine when the dog comes in to lay under my chair and I want to quickly know exactly where she is.
Cheers,
