Camera Orbit with multiple Cameras in scene

I am creating an animation involving lego figures. I have 4 camera within my scene, I want to add a mouse camera orbit to each camera but I don’t know how to do that. Could someone please help me out ASAP. Many thanks in advance.

You could try the Cinemachine package from Unity Technologies. It is a free package for all sorts of camera types and movements, developed specifically to enhance the cinematic capabilities of Unity.

There are decent examples of orbital cameras in the package itself. There is also a tutorial on the Unity website: Cinemachine - Unity Learn
