Adding Gallery to Page

I’m sorry, this seems like such a silly question and I feel ridiculous for having to ask it, but how in the world do I actually add a gallery I’ve created to my pages?

When I go to the page I want to add my gallery to (which is currently private, so I can’t select it from within the gallery setting of where to publish to), and select “add media,” I see an option that says NextGEN Gallery, but from here all it will allow me to do is view and edit the images that I’ve added to the gallery; no shortcode or option to actually add it to the page.

Again, this feels like a ridiculously simple question but I can’t for the life of me figure it out!

Please help!
