Galleria and Theater add-ons not showing as album options

Backlight 4 & 5 Support
#1

I hope this section is for Backlight 5.

I see the Galleria, Theater modules in the Backlight > Modules page, image attached.
I do not see the modules as available templates for albums. I assumed the versions were for an older installation and purchased Galleria but do not see the Install link for the add-on. Am I doing something the wrong way?
p.s. I’m “unable to add a media item to the post”

Are you first creating the templates?

Yes, my bad, I was looking in Album Set templates. I’m creating a template now.
Thank you.

Created a Galleria album, looks fantastic.
