I am testing Deja Dup for backup. I did a full backup and a full restore and it worked fine. However according to this I should be able to restore individual files

It says:

You can also restore individual files from a backup. From a Nautilus file manager window, select a file, click the Edit menu and select “Revert to Previous Version.”
But when I click the Edit menu, the is no option to “Revert to Previous Version.”

What am I doing wrong?
