Looks great but never shows up once installed

I was excited about this plugin, but once I installed and activated it (and confirmed that it shows up in the list of installed plugins), there appears to be nowhere to access it in the WordPress Admin interface. I have searched through every single menu item and all subitems numerous times, as well as looking around a page in edit mode to see if there was a button in the rich text editor or something similar. There appears to be nowhere to access this plugin. Cannot use if I cannot access it to set up the iframe.
Instructions would be great, but unfortunately all that is available for this plugin are the installation instructions.
