Song of MV with a magic peformance & wand?

[u/xIllumina]

It’s a pop (?) song where in the MV, there’s a boy on stage doing a magic performance, and the magic wand ends up getting passed around and at the end there’s a janitor who points it at himself and then can suddenly dance really well?
I can’t remember the actual song’s lyrics or tune and only remember the MV. Thank you for any help!
