Help me to avoid the camera to discover the world boundary

I am following the Tanks! unity tutorial → Tanks - Unity Learn

Inside the game, there is a part where the two tanks drive away from each other. So, the camera starts to get further and further away from the scene until you can watch the world boundary. I would like to prevent that, but I don’t know how to do it. Is there anyone who can help me?

Thanks.

Usually, you have to manually set the positions of your objects and your camera and of course the size of your world and background etc, and you have to try a few times to make that look good.
