Add recently changed mappings endpoint?

[nichtich]

A list of Wikidata edits performed through POST/PUT/DELETE at the mappings endpoint can be queried from Wikidata.

A list of 10 to 20 most recently touched mappings (via Cocoda) could be returned at the /mappings endpoint by default (instead of the currently empty list).

I tried to get the recent changes from the API, but can't get it to work for some reason. It seems that this API is the right one, but filtering the changes by our tag doesn't work:

https://www.mediawiki.org/w/api.php?action=query&list=recentchanges&rctag=OAuth+CID%3A+1358 (no results)

https://www.mediawiki.org/w/api.php?action=query&list=recentchanges&rctag=OAuth%20CID%3A%201358 (no results)

Not sure what I'm doing wrong.
