Powered fan screen removal

[DennisB]

Hi,
I have a 2020 trailmanor with the powered ceiling vent over the door next to the stove-the screen has gotten dirty and I want to remove it for cleaning—there is what looks like a place to pry the screen out on the right side of the unit. I tried to pop the screen out and it wouldn’t release easily, so I backed off for fear of breaking it. I have attached a photo. Does anyone know how to remove the screen? I see no name or manufacturing info so I can’t YouTube the info I am looking for.

Any information would be appreciated

Thanks,
Dennis
