Facebook authentication in App Script

[Hashcrypt Hash]

Hi,

In the app script, I want to add AuthType as OAUTH2 and implement Facebook authentication when users access the data studio. After that, I want to fetch the access token when the user comes back on callback after authentication.

Below is the codebase of app script

=> code.gs 

function getAuthType() {

    var cc = DataStudioApp.createCommunityConnector();

    return cc.newAuthTypeResponse()

        .setAuthType(cc.AuthType.OAUTH2)

        .setAuthUrl('https://www.facebook.com/dialog/oauth') // Your Facebook authorization endpoint

        .setClientId('********709369') // Replace with your App ID

        .setClientSecret('*********03284c09d3') // Replace with your App Secret

    .setScopes(['email', 'public_profile']) // Example scopes, adjust as needed

    .build();

}

var cc = DataStudioApp.createCommunityConnector();

function getConfig(request) {

  var cc = DataStudioApp.createCommunityConnector();

  var config = cc.getConfig();

 

  config.newInfo()

    .setId('instructions')

    .setText('Datablaster.io - Test');

  try{

      var accessToken = request.configParams.accessToken;

      Logger.log(accessToken);

  }catch (error) {

      // Handle the error, e.g., display an error message in the config

      config.newInfo()

        .setId('error')

        .setText('Error : ' + error.message);

      Logger.log('Error :', error);

    }

  config.setDateRangeRequired(false);

  return config.build();

}

function isAdminUser() {

  return true;

}

=> appscript.json

}

Please provide proper documentation and information for how we can achieve this.

Thanks
