How to use "Areas" of Gridmap?

I can see tiles in “Tiles” after loading MeshLibrary.
But, it’s empty if select “Areas” option.
I can see Grid > Create Area menu on toolbar, but it seems not doing anything.
Any tutorial for this?

With shift+left click, you can create selections, then create areas from the selection.

I don’t understand how these areas are used but for the GridMap methods seems that are related to rooms and portals.
