Loading jquery in chome extension service worker manifest v3 - google-chrome-extension

Question

I am having a extension where it can notify about new items added to RSS feed reader
All works in v2, but v3 I am unable to load jquery into service worker, since chrome doesnt allow.
As a workaround I have added as module
"background": {
"service_worker": "js/background.js","type": "module"
},
But still its a issue and says ReferenceError: $ is not defined
at Object.parseFeed
Or is there a way I can tweak my code to read xml without jquery?
import $ as module from 'js/jquery-2.1.4.min.js';
var Storage = (function() {
return {
getFeeds: function(callback, returnArray, sortArray) {
returnArray = typeof returnArray !== 'undefined' ? returnArray : true;

chrome.storage.sync.get(function(dataObject) {
var result = dataObject;
if (returnArray) {
var feedArray = this.parseDataObjectIntoArray(dataObject);
result = sortArray ? this.sortArrayOfObjects(feedArray, 'position') : feedArray;
} else {
delete result['RssR:Settings'];
}
callback(result)
}.bind(this));
},
getFeedByUrl: function(feedUrl, callback) {

Object.keys(object).forEach(function(objectKey) {

array.push(object[objectKey]);
}
});
return array;
},
sortArrayOfObjects: function(array, sortKey) {
array.sort(function(a, b) {
if (typeof a[sortKey] === 'undefined') {
return true;
} else if (typeof b[sortKey] === 'undefined') {

}
return a[sortKey] - b[sortKey];
});
