- recentIntentSummaryView (list) –
  
  An array of information about the intents used in the session. The array can contain a maximum of three summaries. If more than three intents are used in the session, the recentIntentSummaryView operation contains information about the last three intents used.
  
  If you set the checkpointLabelFilter parameter in the request, the array contains only the intents with the specified label.
  - (dict) –

      The name of the intent.
    - checkpointLabel (string) –
      
      A user-defined label that identifies a particular intent. You can use this label to return to a previous intent.
