You can either create one FAQ policy page* or several entry pages. From a chatting librarian viewpoint, it may be easier to beak out sections into their own FAQ entry as they will be listed to view:

Please note: This example chat was started from the AskMN staff resources page, https://elibrarymn.org/askmnstaff/chat, which is the Minitex public chat widget and will pull the Minitex policy pages and public FAQs.
