This Event is emitted in the context of a Resource. It is intended to activate when the user finishes interacting with or seeing the implementation of this Resource. For example, this Event will be called for Screen Message when the message disappears from the screen; or for Media when the Media Item finishes playing.
Although it is best-practice to include it, this Event is not guaranteed to be emitted. This depends upon the implementation of the app. Project templates downloaded from Motive.io will emit it.
