Creative Cloud Files: Screenshots

I've got a feeling this is a really dumb question but I can't find anything on it anywhere.  I have the "Photography Plan" which installed Adobe "Creative Cloud Files" on the side bar in the Finder on my Mac computer.  In it there are two folders, "Files" and "Screenshots".  I get the "Files" part.  But what screenshots get placed in the "Screenshots" folder and how do you generate them?  Thanks in advance.
