RequiresDismissConfirmation

protocol RequiresDismissConfirmation : UIViewController

The RequiresDismissConfirmation protocol can be implemented by view controllers that are managed by the ExposureSubmissionCoordinator to react to dismissals (either by pressing the close button or the swipe down gesture). The protocol comes with a default implementation that displays a generic confirmation popup.
