Editing Prefabs

I noticed in the course whenever changes to the asset in the hierarchy were made the instructor could click on “apply” to apply those changes to the prefabs in Assets window. I’m on 2018.4.17f1 and I am not seeing that in the inspector.

I did notice a “>” next to the right-side border of the hierarchy window that when you click you can edit just the object/asset itself. It seems to save to the prefab but I’m not 100% if that’s the current method.

Is this the new method?
Thanks.

PS: Sorry if this has been asked/answered already, I didn’t find anything in the discussion for this lecture.
