black locust

Hi all, I accidentally snapped of the tip of the currently leader branch on this black locust. It’s a young tree - wondering if I need to do anything to help it or still let it go. The leader is still taller than the other branches. I’ve attached some photos! Thanks in Advance

Hello, Could anyone confirm if this is a black locust? If not, what kind of tree is it? I live in West Michigan. Thanks!
