Question Quest 2 Passthrough only works for stationary boundary on my unity project

I am new to Unity and developing for the Meta Quest 2. I created a simple MR scene with pass-through enabled and an interactable object but encountered 2 issues.

1: Passthrough only works in my app for a stationary boundary, when I switch to room-scale boundary I get a black background.

2: Every time I open my palm a pop-up stating 'allow connected devices to access files' appears for a few seconds. It cannot be interacted with and disappears on its own after a few seconds. My Quest is not connected to anything, and it is offline.

Does anyone have any idea how to get around these?

 

I also got a black background and also seeing purple tracing of the things around me. And when I look up, the cieling appears.
Then I finally figured out. I solved the problem by closing the Space Sense in the setting to prevent Oculus to detect the things within your roomscale boundary.
{setting/ physical space/ boundary/ Space Sense}
Hope it helps.
