In the documentation, the last step before rerunning all the tests are `Now run ddev composer require 'drupal/ai:1.3.x-dev@dev' to get the latest changes in the 1.3.x branch.` After this we should add that you need to build the three different components - MDXEditor, JSON Schema Field and AI CKEditor.
