Missing page

I’m trying to add the Sunshine plugin for client galleries, but I can’t see where it’s installing on my site. I can pull up a “client” page with a direct link where I think it’s going, but not from the home page or any of the dropdown pages. I have a “galleries” tab on the home page with a dropdown list of different galleries, and this is where I’d like the client galleries to go, however, this galleries tab isn’t on my pages list either on my dash, although all the other pages are listed. Hopefully this make s sense…help.
