| AmazonWorkflow | This API is intended only for use by Login With Amazon-enabled SDKs. | 
| BaseWorkflowListener<T, U, V> | To create your own interactive workflow, extend this listener and implement all abstract methods besides onSuccess,onCancel, andonError(which will be implemented by the app
 developer). | 
| WorkflowCancellation | If an interactive workflow is cancelled from the Login With Amazon SDK's perspective, ERROR(/InternalInteractiveListener#onRequestCancel)will be called, returning an instance of this type. |
