unity doesn't show preview

Question

My question is quite simple. I am learning Unity and watching a tutorial about making a 2D game.

In the tutorial, there is a Preview section at the bottom right corner. But in my Unity, there is nothing there. There is Inspector on the right and below of Add Component there is nothing.

This is what I want:

This preview box is for resources. It shows a preview of the resource. To get this to show up you must click on one of your resources(Like an image).

However when you do not have a resource selected it will not show up
