Adding custom CKEditor build produces Uncaught SyntaxError: Cannot use import statement outside a module error

I am trying to add a custom CKEditor to a ckeditor field in my setupCreateOperation() in laravel Backpack. I am following the guide in the documentation. However, I get the following error in my javascript console: Uncaught SyntaxError: Cannot use import statement outside a module.

As far as I can deduce the problem stems from the fact that the javascript code which the CKEditor Builder generates includes several import statements for the plugins:

ClassicEditor.create(document.querySelector('#editor'), editorConfig);

When adding the file to the custom_build option for the ckeditor field, the field then calls the directive @basset(public_path('assets/js/ckeditor/ckeditor.js')) in the ckeditor field blade. The directive then smartly finds that it is a javascript file and ads the following script to the page:

<script src="http://0.0.0.0:5173/public/assets/js/ckeditor.js"></script>

However there are no type=’module’ on this script, so the error occurs.

Does anyone know if there are anyway to force a type=”module” on the script tag without manipulating with laravel backpack’s source files?
