How to make object lag behind camera?

I’m working on a game with my dev team, and we ran into a problem. We want to have it to where when you move the camera with your mouse, it moves, but a child of the camera will in a way lag behind. It will have a slower speed, and not reach the final destination for another second. Thank you for your help!

Maybe it shouldn’t be a child of the camera, but just different object, and just add a script for it to follow the camera with a little delay?
