## Problem/motivation Follow-up or perhaps a replacement to: #3569310 We want to allow users to use a source for their markdown (e.g. MD, PDF, text file, URL). Document Loader has integrated with MDXEditor to make this easy: [#3580850](https://www.drupal.org/project/document_loader/issues/3580850) This has been fixed and there's a new release (2.0.1) that includes it. Hooks were also added: [#3585786](https://www.drupal.org/project/document_loader/issues/3585786) so we can save the source. ## Solution **IMPORTANT: The integration should be done using progressive enhancement. We should not have a hard dependency on Document Loader.** Integrate with Document Loader so that the MDXEditor button shows up for in CCC editor and we save the source in the context item content entity. ## Tasks - Update code - Review code - Manually test code ## AI usage - [ ] AI assisted issue - [ ] AI assisted code - [ ] AI generated code
