Action functions allow you to write custom buttons to the message toolbar for end users to interact with. This feature enables more interactive messaging, enabling users to grant permission before a task is performed, generate visualizations of structured data, download an audio snippet of chats, and many other use cases.

A scaffold of Action code can be found in the community section.

An example of a graph visualization Action can be seen in the video below.
