You can scale it however your like. I originally printed white one 200x200x3 and black one 200x200x5 on my Ender 3 v2 and both turned out fine. Viewing cone is higher the thinner it is.

As a setting I used 0.1-0.3mm adaptive with ironing, nothing too special. And make sure Z position is at 0. I suggest you to use the best quality your printer can bend to for satisfying result.
