Good question, however this was fixed in a different way in Bug#56123

recentf-list directly instead.

Yes, I saw a need for a rethink of the documentation, which was very
menu-centric.  So I rewrote it slightly to be less menu-centric; I
hope it now makes more sense.

Please find attached a new patch, and thanks for reviewing.
