Disconnecting a Connect-my-Mac session

Pardon my ignorance on a basic question, but how do you *disconnect* a Connect-My-Mac session on an iPad?
I did not see a button or instructions for doing this anywhere. Seemed the only way I can proceed is to shut down the app. (And in trying to disconnect, it is very to easy to mess up something on my remote Mac's screen display.)
Thank you for your help.
