Removal of the right side of the case of an Officejet Pro 8625?

I cannot for the life of me figure out where to unlock the right (*edited) side panel near where it attaches to the paper feeder. I see the tabs on the underside and the entire thing is separated except in that area where the light grey part I’m trying to pry apart presses against the black plastic for the paper feeder.

I’ve been able to remove the left panel and back panel with no issues, just stuck on this side here. Anyone have any tips?

Thank you ahead of time for any help!
