Action Buttons and Links
Action buttons and action links let you execute custom code in your chat. They're perfect for creating quick-response actions, such as polls, approving requests, or marking items as done.

Action buttons in an in-chat poll
On React and Web Components, action buttons and links are available to use inside message content.
If you're using Flutter, React Native, or the Classic JavaScript or React SDK, then you can add action buttons and links both to message content, and to the chat header, message field, conversation list header, and conversation list items.
