Helpers tell the voice assistant to momentarily take over the conversation to obtain common data, such as a user's full name, date and time, or a delivery address. See also Actions on Google Helpers for the JSON of helpers.
You can configure a helper to trigger an intent without users having to invoke the intent.
To add a helper intent to Dialogflow console:
In the Dialogflow console, add the intent for which you need helpers.
Add a respective event to that intent.
Click Save.
In the Experience Designer, select a flow.
Drag a function node to the canvas.
Copy the JSON code (see sample code below) and paste it into the function node.
Connect the function node to wherever applicable. The following image shows a sample flow.
Deploy the flow.
The following code creates a helper intent that creates a list, from which users can select an option, for smart display devices such as in the following image.

msg.alexaResponse.response.payload.google.systemIntent = json.payload.google.systemIntent;
return msg;If you get the value in payload.orginalRequest.source as google, then inject the JSON code into the response object.
