Pop up works on the site owner wants it to only open twice

Pop up works on the site owner wants it to only open twice during visit but be available from a link with a picture as the button. how do we accomplish this with this plug in should be easy since the plugin sets a cookie the button could just clear the cookie and refresh the screen but we have know idea how to access the cookie that was created what are the values pulled from. I know I can find it if I take the time to really dig through the plugin but I was hoping someone would have a fast answer that will not tie me up time wise.
