  - cancel
```
 abstract void cancel(Consumer<GliaException> callback)
```
    Cancels Visitor's Engagement Request.
    Behaves the same as if cancelEngagementRequest was called with this Engagement request ID value.
    
    Parameters:
    
    callback - Called with {@code null} if request succeeds or with GliaException if failed.
  - getId
```
 abstract String getId()
```
    Returns Engagement Request unique ID
  - getOutcome

 abstract Optional<EngagementRequest.Outcome> getOutcome()
```

  - on
```
 abstract <T> void on(EngagementRequest.EngagementRequestEvent<T> event, Consumer<T> listener)
```
    Registers event listeners for Engagement Request.
    If a listener is added while the Engagement Request is processing an event,it is not triggered with the current event.
    If multiple identical listeners are registered on the same event typethe duplicate instances are discarded. They do not cause the listenerto be called twice and do not need to be removed with the off method.
    
    Parameters:
    
    event - One of Events
    
    listener - Event listener to register
  - on
```
 abstract void on(EngagementRequest.EngagementRequestEvent<out Object> event, Runnable listener)
```
    Registers event listeners for Engagement Request.
    If a listener is added while the Engagement Request is processing an event,it is not triggered with the current event.
    If multiple identical listeners are registered on the same event typethe duplicate instances are discarded. They do not cause the listenerto be called twice and do not need to be removed with the off method.
    Compared to on this methoddoes not require the listener to consumer the payload.This is useful when payload is of type Void.
    
    Parameters:
    
    event - One of Events
    
    listener - Event listener to register
  - off
```
 abstract <T> void off(EngagementRequest.EngagementRequestEvent<T> event, Consumer<T> listener)
```
    Removes event listeners from the Engagement Request.
    If an event listener is removed while the Engagement Request is processing an event,it is not triggered with the current event.
    Calling {@code off} with arguments which do not identify any currently registeredlistener has no effect.
    
    Parameters:
