The only thing I saw was a white flag/poster with a 5 pointed red pentagram hanging on the wall. Was that the item that you are reffering to?
That appears several times. But at 30-31 seconds it’s (this other thing - similar but distinct) fully visible for less than a second and then partially-visible as it passes out of frame to the right as the camera pans left. The full view is there, completely, but for such a short period of time. You can adjust the controls in YT. This machine is messed up (the OS) or I could do it easier for myself. Took me several tries to get the full pic.

That’s the “something else” I referred to. Yes, that one seems to be panned about a dozen times.
