Adding people and publications

I’m trying to add lab members to the “People” page and lab publications to the “Publications” page using the YaleSites pre-built features. I enabled the required modules, yet when I try to add people, for example, I can’t access the “People” menu mentioned in these instructions. When I try to add publications (following these instructions), there is no “Faculty publications” option under “Add content.” Do I need to enable anything else, or do I not have the appropriate permissions to do this? Thanks!
