    Procedure

    1. Navigate to All > Conversational Interfaces > Assistant Designer.
    2. Select the Asset library tab.
    3. Set the topic discovery toggle switch to NLU/Keyword.
    4. Select Test Topics.
    5. Type an utterance that should trigger the Google Dialogflow intent that is mapped to the topic.
    6. To test entity slot-filling, do the following:
      1. On the Flow tab, add a Text user input node.
      2. Select an entity for the NLU entity field.

      Ensure that the entity you select is configured in your Google Dialogflow ES agent. When a matching utterance is entered in the Test this topic window, the topic should be triggered, and the entity should slot-fill automatically.
