How to move the camera correctly in a 2D game, taking into account the height differences?

Question

C++ / C#

Greetings, there is a game where the camera moves when you click on the right side of the screen to the right, and vice versa when you click on a part. I can't catch up, how to move it, taking into account the height differences of the game world? I already even tried to hang a RigidBody2D with a collider on the camera, and imitate the rails on which it rides, but when I hang a rigidbody, any collider does not respond to pressing within the camera.
I will be very grateful for the answer.
