how to restrict the employee to not request more than 2 requests for non catalog learning in VBS

Summary:

I Tried by this code and put it in action chain then associated with event listeners using vb enter but nothing happened

define([
'vb/action/actionChain',
'vb/action/actions',
'vb/action/actionUtils',
], (
ActionChain,
Actions,
ActionUtils
) => {
'use strict';

class request_learn extends ActionChain {

/**
 * @param  {Object} context
 */
async run(context) {
  const { $page, $flow, $application } = context;


  const result = await Actions.callRest(context, {
    endpoint: 'siteHcmExtensionNonCatalogRequest/getall_learnerLearningRecords',
    uriParams: {
      q: "AssignmentType='ORA_NON_CATALOG' and LearnerId='" + $application.user.personId + "'",
    },
  });


  if (result.body.count >= 2) {

    await Actions.fireNotificationEvent(context, {
      summary: 'تنبيه: تم تجاوز الحد المسموح',
      message: 'لا يمكنك تقديم أكثر من طلبين للتعلم خارج الدليل (Non-Catalog).',
      type: 'error',
