How to get the caller ID of caller using OriginalDetectIntentRequest api of google dialogflow in node.js

Question

When a user calls to the Dialogflow phone gateway, I should be able to retrieve his phone number. So, I referred to the Dialogflow version 2 API's and I found one API called OriginalDetectIntentRequest which stores the called ID in the payload. I need the node.js code to retrieve this caller ID. (I'm new to Dialogflow and node.js). Can anyone provide me with the code for it.
