How to use the azure-storage.QueueUtilities function in azure-storage

'use strict'

require('dotenv').config()
const azure = require('azure-storage')

const storageConnection = process.env.AZURE_STORAGE_CONNECTION_STRING
if (!storageConnection) {
  process.exitCode = -1
  console.error('env var $AZURE_STORAGE_CONNECTION_STRING is required')
}

const queueName = process.env.QUEUE_NAME || 'completed-checks'
const permissions = azure.QueueUtilities.SharedAccessPermissions.ADD

var queueService = azure.createQueueService(storageConnection)
// setCors(queueService)

const generateSasToken = () => {
  // Create a SAS token that expires in an hour
  // Set start time to five minutes ago to avoid clock skew.
  var startDate = new Date()
  startDate.setMinutes(startDate.getMinutes() - 5)
  var expiryDate = new Date(startDate)
  expiryDate.setMinutes(startDate.getMinutes() + 60)

  var sharedAccessPolicy = {
    AccessPolicy: {
      Permissions: permissions,
      Start: startDate,
