Using an Xbox wireless controller with iPad/Mobile

My son plays Minecraft on his ipad and given there are no xbox series x consoles on the market at the moment, we bought him an xbox wireless controller to use with it. I did research and as long as the ipad has ios version14+ then it should work (which it does). The controller connects fine to the ipad but we can’t get it to work in Minecraft. Can anyone help please?
