Close the select2 dropdown only when clicking on a specific button [duplicate]

I am using the Select2 jQuery plugin to create a dropdown. I have multiple dropdowns on my page.

I want the dropdown to close only when licking on ‘Apply’, ‘Cancel’ or ‘Reset’ buttons. I don’t want the dropdown to close when clicking anywhere else.

Note: when testing on StackOverflow environment it is working as I require, but not in Chrome.

var temporarySelection = [];
var temporarySelection_level1 = [];
var temporarySelection_level2 = [];
var temporarySelection_level3 = [];
var startDateText = '';
var endDateText = '';
var selectedTextAward = '';
var selectedTextOrg = '';
var selectedTextPillar = '';
var selectedTextLeader = '';
var selectedTextTeam = '';
var selectedDateOpt = '';
let filterRequest = '';
var pillars = [];
let badgifyData = '';
let pageHomeAward_filter = 1;
// let jsonData = '';
function formatState(state) {
  if (!state.id) {
    return state.text;
  }
  var selected = ($('#mySelect').val() || []).indexOf(state.id) !== -1;
  var $state = $(
    '<span><input type="checkbox" class="select2-checkbox"' + (selected ? ' checked' : '') + ' /><span class="select2-checkbox-label">' + state.text + '</span></span>'
  );
  return $state;
}


function formatSelection(selected) {
  return selected.text;
}


$(document).ready(function() {


  //get the csv for dropdown

  const select2Input = document.querySelector('.select2-container .select2-search input[type="search"]');
  if (select2Input) {
    select2Input.style.caretColor = 'transparent'; // Set caret color to transparent
  }
  $('#mySelect').select2({
    placeholder: "Select",
    templateResult: formatState,
    templateSelection: formatSelection,
    closeOnSelect: false,
    minimumResultsForSearch: -1,
    allowClear: false
  });

  // Event handler for opening the dropdown
  $('#mySelect').on('select2:open', function() {
    if (!$('.apply-button').length) {
      $('.select2-dropdown').append(
        '<div class="select2-footer">' +
        '<button class="clear-button">Reset</button>' +
        '<button class="cancel-button">Cancel</button>' +
        '<button class="apply-button">Apply</button></div>'
      );
    }

    // Event handler for Apply button click
    $('.apply-button').off('click').on('click', function(e) {
      // Perform actions you need
      $('#mySelect').select2('close'); // Close the dropdown after applying
      // Example action:
      temporarySelection = $('#mySelect').val() || [];
      console.log("Applying selection: ", temporarySelection);
    });

    // Event handler for Clear button click
    $('.clear-button').off('click').on('click', function(e) {
      // Perform actions you need
      $('#mySelect').val(null).trigger('change'); // Clear selections
      // Example action:
      temporarySelection = [];
      console.log("Clearing selections");
    });

    // Event handler for Cancel button click
    $('.cancel-button').off('click').on('click', function(e) {
      // Perform actions you need
      $('#mySelect').select2('close'); // Close the dropdown after cancelling
      // Example action:
      console.log("Cancelling");
    });


  });


  $('#mySelect').on('select2:select', function() {
    temporarySelection = $('#mySelect').val();
    console.log("tempsel", temporarySelection)
  });

  $('#mySelect').on('select2:unselect', function() {
    temporarySelection = $('#mySelect').val();
    console.log("tempUnsel", temporarySelection)
  });
