Front panel metal bracket stuck while trying to remove the screen

The plastic circle thing goes for the front camera for aligning to the screen glass camera hole.

You will notice this if you look at the front camera carefully and it's notches.

There's another plastic gasket which is rectangle for the proximity sensor next to camera on the same front camera assembly.

I advise using razor blades to pry on sides of screen (between metal housing and screen assembly to pry it up as worn out / damaged screen frames don't separate well with suction cup method.
