First of all welcome to the board. I hope you will find it educational and fun. There is a lot of good info here and a lot of just funning around.
Now for your question, I have no idea. I haven't had to take off the newer ones so I don't know. The older ones used to have little buttons that you had to pull out. I would say just take something a pry the edge up so you can see in and see what is holding it there.
The older ones have little buttons that you just have to get like a screwdriver or they make a puller for it under it or next to it and just pry.
Good luck.
