Im using React. Installed according to these instructions, used online builder: Integrating a build from the online builder
I'm trying to add a double click event listener on editor using this instruction: How to listen on a double-click?.
When I try to import: import { DomEventObserver } from 'ckeditor5/src/engine';,
I get an error:Uncaught CKEditorError: ckeditor-duplicated-modules
What am i doing wrong?
