Can't edit "our story" business page

Hey everyone I am doing an update for my wife's Facebook business page and I cannot seem to find where to edit the "our story" section. I've tried several different browsers I can only see that section on the mobile version of the site but not on the browser. Can anybody tell me where to find this on the desktop version so I can edit it. I have watched multiple videos and they are all old and Facebook has gone through several updates since then.
