Message Actions

Message Actions

Overview

In most cases, actions are available for messages from the assistant, and CUI Kit provides you with all the necessary functionality so that you can customize them to suit your needs.

Assistant’s actions

By default, only copying the assistant’s message in markdown/HTML format is available. You can hide this feature by passing the disableMessageCopying prop. You can create your own actions by passing an array of React.JSXElementConstructor in the assistantActions prop. Your component will receive n props the assistant’s message that the user interacts with, and the current thread.
