Ready to publish content is content that has been thoroughly reviewed and is waiting to be published to your live chatbot.
Content at this stage can't be edited: if you make changes, the content will automatically be moved back to draft. Publishers and Admins can then move the content back to ready to publish.
When you change your chatbot Experience settings, they are automatically sent to ready to publish. These changes can't be sent back to ready to review or draft and must be published with the next version of your chatbot.
You can view all your changes that are ready to publish using the Ready to Publish section of Versions.
