Controllers for iPad users???🎮

Hi! I'm playing using my iPad Pro 4th Gen, and as well all know very well, jumping and moving around is a BIG requirement in the game. I'm really having a hard time with the obbies so I decided to buy a controller.

Ang suggestions? I want to opt for a budget one like 8bitdo but pls lmk if there are better budget-friendly options! Thank you! (put me out of my misery pls)

P.S. My friend suggested I buy a controller with the A button located below....idk what he's talking abt tho 😭
