What is the best way to use special attacks on XBox?

Some of my tools in my game have special attacks that can be activated by pressing Q,E,R,Z etc. How would I go about letting Xbox players activate their special ability? I don’t have an XBox so I don’t really know how others go about this.

Probably using R1, L1, X, Y, etc… I don’t really develop games for XBox so I can’t help you that much.
