Installing CKEditor plugin in Laravel project

I am working on Laravel project that uses WYSIWYG editor (CKEDITOR). The problem I ran into is that I can't resize imported image in the editor itself.

In the official documentation I found out, that I need to install custom plugins for each missing functionality.

But so far I could not find a way to import any of official plugins into my Laravel project.

My current configuration is:

webpack.mix.js

mix.js('resources/js/app.js', 'public/js')
    .sass('resources/sass/app.scss', 'public/css');

resources/js/app.js

import ClassicEditor from '@ckeditor/ckeditor5-build-classic';
window.ClassicEditor = ClassicEditor;

With this content of app.js the CKEditor works fine without using plugins.

Then I tried adding import for the specific plugin:

import ImageResize from '@ckeditor/ckeditor5-image/src/imageresize';
window.ImageResize = ImageResize;

But that resulted in throwing an error: Uncaught CKEditorError: ckeditor-duplicated-modules It also provided link to their documentation containing that error, where I realized that you can import the source file (@ckeditor/ckeditor5-editor/src/classsiceditor) or the build file (import ClassicEditor from '@ckeditor/ckeditor5-build-classic';), but here is where my understanding of what is going on faded away.

Anyway I also tried using the plugin in the view:

ClassicEditor.create(
      allEditors[i], {
        plugins: [ ImageResize],
        extraPlugins: [SimpleUploadAdapter]
      }
    );

But since it's not correctly imported it doesn't really matter.

I also found that Stackoverflow question from almost 3 years ago with similar problem, but no answers.

Any help will be really appriciated. Meanwhile I will also try some other WYSIWYG editors, and if any of those will be more promising will probably end up using one (will let you know here as well).
