title: How do i send a email on same thread using google-api-nodejs-client nodejs
body: <p>I have full response of a email send using node module google-api-nodejs-client, which is like 
  <code>
  {
    "id": "1231212312", 
    "labelIds": ["UNREAD", "SENT", "INBOX"], 
    "threadId": "23123123"
  }
  </code></p>
  
  <p>I need to send an email again to the email address but in the same thread not as a new email.</p>
  
  <p>I checked the documentation but wasn't able to find relevant stuff.</p>
  
  <p>Here is the link to its documentation: <a href="https://github.com/google/google-api-nodejs-client/blob/master/apis/gmail/v1.js#L796" rel="nofollow noreferrer">https://github.com/google/google-api-nodejs-client/blob/master/apis/gmail/v1.js#L796</a></p>
  
  <p>Thanks!</p>
