removing rear step pad on 98 SN

I could use some help figuring out how this part comes off the boat. I have the tank out for other work right now and want to remove the step for some cleanup under and around it. From underneath I can see screes coming thru the fiberglass around the very outside edge of the whole cover. It looks like there is hard plastic and then a thinner softer cover on this. Is this just stuck down with some kind of adhesive or ???
Thanks for any help you can provide.

Must be different than the 95, they are definitely screws and not studs with nuts. Sharp pointy screws, the kind that make me bleed a lot. No foam to deal with either. You can see in this picture the 2 screws on the starboard side of the step are red circles, and the blue screw is for the vent which is not part of the step assembly.
It looks like I would have to peel the softer cover off to get at the screws. But don't want to try that and end up having to try and find a new one.
Thanks for the reply and help. !!!!

Here you go. As mentioned above; you'll ruin the rubber when you remove it so you will need to order a piece and cut to fit. There was no silicone underneath, it just dropped off.   I used this outfit for the plate and to replace the gunwhale step pieces ( https://www.hydroturf.com) - I just bought a small sheet and cut to fit but I've got an idea to replace all with seadek but can't be bothered to template and they haven't patterned the TSC hull.
