How change Angularjs CKEditor with custom directive and ng-ckeditor for ckeditor 4.24.0 version

I found Angularjs CKEditor Example with custom directive and ng-ckeditor in this link but this example work only until ckeditor 4.22.1 version and not work with ckeditor 4.24.0.

https://codepen.io/navin_sh/pen/RKQweE

cdn.ckeditor.com/4.22.1/standard/ckeditor.js
ajax.googleapis.com/ajax/libs/angularjs/1.8.3/angular.js

Ckeditor tell older version befor ckeditor 4.24.0 have security issue and i want use latest version.

What changes should I make in this script so that it can work with version 4.24.0?
