Looking for a follower script

Hello friendly people, I want to create an object, like a bot that sits behind your shoulder and follows you around. I had one once in another follower object call wild slime follow drone, where you could turn follow on or off by voice command but seem to have misplaced it. That one though didn't rotate the follower as the avatar it was following rotated. It just moved with the avatar. I would prefer one where it follows the avatar's rotation as well. Would anyone be able to help please.
