[Koha] Catalogue statitistics by Catataloguer Name

Hi Hope I find you well. I have a super librarian who has four cataloguers and is interested in establishing the number of items catalogued by each cataloguer on a weekly and monthly basis. Is there anyone who have come up with such a query. Or alternatively, can someone formulate the query for me, for I am at a loss. Regards, Admire Mutsikiwa University of Zimbabwe
