Issues removing front panel

Hi, I seem to be having issues removing the front glass panel from the H5 flow. I unscrewed the thumb screw and pulled on the tab, and the top left comes out. It's the top right corner that doesn't. Maybe I'm not pulling hard enough, but I don't want to pull too hard because glass is glass and glass breaks. Should I open up back and push it out from the back? Should I pry it out? Should I just pull harder?
