How to use the keen-tracking.debug function in keen-tracking

private initKeen() {
    const { projectId, writeKey } = environment;
    
    this.client = new Keen({
      projectId,
      writeKey
    });

    if (!environment.production) {
      Keen.enabled = false;
      Keen.debug = true;
  
      this.client.on('recordEvent', (event, data) => {
        console.log('event:', event);
        console.log('data:', data);
      });
    }

    const timer = Keen.utils.timer();
    timer.start();
    
    // Batch-record events every 5s
    this.client.queueInterval(5);

    this.client.extendEvents(() => {
      return {
        geo: {

// Record all mutations to a single event stream
const EVENT_STREAM_NAME = 'app-mutations';

// Omit noisy mutations if necessary
const OMITTED_MUTATIONS = [
  // 'KEYPRESS',
  // 'WINDOW_RESIZED'
];

// Define a client instance
const client = new KeenTracking({
  projectId: 'YOUR_PROJECT_ID',
  writeKey: 'YOUR_WRITE_KEY'
});
// Optional debugging
KeenTracking.debug = true;
client.on('recordEvent', Keen.log);

// Track a 'pageview' event and initialize auto-tracking data model
client.initAutoTracking({
  recordClicks: false,
  recordFormSubmits: false,
  recordPageViews: true
});

const vuexLogger = store => {
  // Called when the store is initialized
  store.subscribe((mutation, state) => {
    // Called after every mutation.
    // The mutation comes in the format of `{ type, payload }`.
    const eventBody = {
      'mutation': mutation,
