Where is the Multisite Theme Manager generated 'theme'

Where is the Multisite Theme Manager generated ‘theme’ page?

I have set up this plugin and takenit out of set up mode. From the setting page it gives options for labelling: Theme Page Title etc. i called it Themes.

The DEV site I have is here http://hosting.photography/ so I am assuming that the generated themes pages as mentioned should be here http://hosting.photography/themes

Only it is not and gives an unfound message error.

Where is this page then please? No page is showing in the menu either.

I wanted to put a page in the Front end that lists what themes are available with which plan.

I am now thinking that sadly this plugin does not do that as I expected.
