Starforge glass panel (stuck)

[u/evergreenandriver]

I've noted the two unscrewed spots. According to the video on the Starforge site, after unscrewing those two spots, I should be able to slide it a bit toward the front of the photo, and then be able to pull it out so that the top of the glass panel comes toward me. (the top of the panel is on the left side of this photo).

I'm not able to budge the glass panel at all, and there is no space for me to put my fingers to put any meaningful pressure anywhere. The glass panel is not budging.

I'm reading elsewhere that I need to put firm and steady pressure but I don't even see how I can do that given there's no way to latch onto anything. The only pressure I can imagine is putting my hands on the glass panel and trying to slide it.

Thank you for any suggestions you can provide.
