For gmails api, add this to nodejs code:

function getUsersEmail (auth) {
  const gmail = google.gmail({version: 'v1', auth})
  gmail.users.getProfile({
    userId: 'me'
  }, (err, {data}) => {
    if (err) return console.log('The API returned an error: ' + err)
    console.log(data.emailAddress)
  })
}
