how to remove fascia boards from top of slide

Hi,
I have a 2016 Keystone Passport Ultralite.
I need to remove the long decorative fascia boards that are attached to the top of the slide. The middle piece to access the motor in the center of the slide has two screws. But the two long horizontal pieces on either side of the center decorative piece...well, I'm not sure if there are screws there, or is the 1/2" pressboard attached another way? If anyway can help that would be great. Thanks
