"May as well give it a go" is correct and something a British person would say. An American would say "may as well try it out" or "might as well try it out" or "might as well try"

Yeah" give it a go" is an idiom means try to do something

Thank you a lot Patrick :) take care

Yes - something like, “It can’t hurt to try” or “There’s no risk if I try it.”
