Do whatever cleanup is necessary in the callback that happens when the interaction is finished, see http://stackoverflow.com/questions/35238759/prism-custom-confirmation-interaction/35239947#35239947 for a code example – Haukinger Jul 22 '16 at 10:58

Inherit the Interactivity class, then override the getwindows method, pass your custom INotification that contains the window.
