Here are two articles that I found extremely helpful for fiddling with page numbering in Word:

1. “How to view, insert, or remove section breaks in Microsoft Word documents”:
https://www.digitalcitizen.life/how-view-insert-move-section-breaks-word-documents/

2. “Add different page numbers or number formats to different sections”:
https://support.microsoft.com/en-au/office/add-different-page-numbers-or-number-formats-to-different-sections-bb4da2bd-1597-4b0c-9e91-620615ed8c05

That is all.
