ReferenceError: ConferenceDataService is not defined

Question

I am trying to develop google calendar add-on like zoom meeting.

In appsscript.json file, below code is there.

 "calendar": {
      "conferenceSolution": [{
        "onCreateFunction": "createConference",
        "id": "1",
        "name": "Meeting",
        "logoUrl": "https://companyxyz.com/images/logo192.png"
      }],
      "eventOpenTrigger": {
        "runFunction": "buildSimpleCard"
      },
      "currentEventAccess": "READ_WRITE"      
    }
  }

In Calendar.gs, below code is there.

function createConference(e) {
  Logger.log(e);
  var dataBuilder = ConferenceDataService.newConferenceDataBuilder();
  return dataBuilder.build();  
}
/**
   * Build a simple card with a button that sends a notification.
   * This function is called as part of the eventOpenTrigger that builds
   * a UI when the user opens a Calendar event.
   *
   * @param e The event object passed to eventOpenTrigger function.
   * @return {Card}
   */
  function buildSimpleCard() {
    var buttonAction = CardService.newAction()
        .setFunctionName('onSaveConferenceOptionsButtonClicked')
        .setParameters(
          {'phone': "1555123467", 'adminEmail': "[email protected]"});
    var button = CardService.newTextButton()
        .setText('Add new attendee')
        .setOnClickAction(buttonAction);
    var buttonSet = CardService.newButtonSet()
      .addButton(button);

    var section = CardService.newCardSection()
               .setHeader("addon")
            .addWidget(buttonSet);

   var card = CardService.newCardBuilder()
      .addSection(section)
      //.setFixedFooter(footer);

   return card.build();
    // Check the event object to determine if the user can set
    // conference data and disable the button if not.
  //  if (!e.calendar.capabilities.canSetConferenceData) {
     // button.setDisabled(true);
 //   }

    // ...continue creating card sections and widgets, then create a Card
    // object to add them to. Return the built Card object.
  }

  /**
   * Callback function for a button action. Sets conference data for the
   * Calendar event being edited.
   *
   * @param {Object} e The action event object.
   * @return {CalendarEventActionResponse}
   */
  function onSaveConferenceOptionsButtonClicked(e) {
    var parameters = e.commonEventObject.parameters;

    // Create an entry point and a conference parameter.
    var phoneEntryPoint = ConferenceDataService.newEntryPoint()
      .setEntryPointType(ConferenceDataService.EntryPointType.PHONE)
      .setUri('tel:' + parameters['phone']);

    var adminEmailParameter = ConferenceDataService.newConferenceParameter()
        .setKey('adminEmail')
        .setValue(parameters['adminEmail']);

    // Create a conference data object to set to this Calendar event.
    var conferenceData = ConferenceDataService.newConferenceDataBuilder()
        .addEntryPoint(phoneEntryPoint)
        .addConferenceParameter(adminEmailParameter)
        .setConferenceSolutionId(1)
        .build();

    return CardService.newCalendarEventActionResponseBuilder()
        .setConferenceData(conferenceData)
        .build();
  }

I have published this add-on from Publish->Deploy from menifest.

Executing this code giving me error of ReferenceError: ConferenceDataService is not defined.

I have searched all the possible references, but not able to get any solution. Please suggest me proper solution for this.

According to this comment from this issue here, it looks like there has been a change regarding this.

When testing the above code, the ReferenceError: ConferenceDataService is not defined. is not displayed anymore and the code runs as expected.

For other methods specific to the ConferenceDataService you can check the documentation here.
