I want to put a small screen with a zoomed out camera view in my 2d platformer

So I would have sworn I saw this asked before, but I've searched a lot and cannot seem to find it, so I'll go ahead and ask...

I was wondering how to put a small screen in the corner of the the whole screen that shows a zoomed out perspective of the level, to make it easier to navigate?

Any help would be greatly appreciated!

Add a second camera, change the view rectangle (normalized view port?) and the depth on the small one

(play with these settings in the inspector)
