Editor for clients and hidden content

Editor (for clients) question - I used an accordion to create FAQs on a page.

The client would like to change the text for the Answer that is hidden by default. Is there a way they can access the hidden part that doesn’t display by default. I can do this myself in the Designer but the client wants to be able to do this himself. If you scroll to the bottom of my site, you’ll see the 2 FAQs https://www.chiropractorsannapolis.com/pregnancy
