How to get speakertag from google speech to text longRunningRecognize method?

This is the code i'm using

const speech = require('@google-cloud/speech');

const client = new speech.SpeechClient({
  projectId: Meteor.settings.private.googleCloud.projectId,
  keyFilename: getFilePath('google-cloud.json')
});

const config = {
  "enableWordTimeOffsets": true,
  "encoding": "WAV",
  "languageCode": "en-US",
  "sampleRateHertz": 44100,
  "model": "video"
};

const audio = {
  uri: "gs://my-project-name/jeff_bezos_1_mono.wav",
};

const options = {
  config: config,
  audio: audio,
};

client
  .longRunningRecognize(options)
  .then(data => {
    const operation = data[0];
    console.log('got a promise representation', data);

    const errorHandler = err => {
      console.log(err);
      throw(err)
    }
    const completeHandler = longRRResponse => {
      console.log('**** response ****');
      console.log(JSON.stringify(longRRResponse, null, 2));
    }
    const progressHandler = (metadata, apiResponse) => {
      console.log('progress ', metadata);
    }
    operation.on('error', errorHandler)
    operation.on('complete', completeHandler)
    operation.on('progress', progressHandler)
  })
  .catch(err => {
    console.error('ERROR:', err);
    fs.unlink(name);
  });

this is the following response I got back

{
  "results": [
    {
      "alternatives": [
        {
          "words": [
            {
              "startTime": {
                "nanos": 100000000
              },
              "endTime": {
                "nanos": 700000000
              },
              "word": "your"
            },
            .
            .
            .
          ],
          "transcript": "your goal is to be the largest online and you are retailer in the world 

beyond that what's the goal for our mission is Earth's most customer-centric 

company and I know what that mean I'll give you an example",
          "confidence": 0.9520494341850281
        }
      ]
    },
}

I did not find any information about speakerTag in response or how to get back speakerTag information from API?
In google api-explorer for recognize there is option to select speakerTag in the fields section

Thanks!
