assistant_thread_started

Assistant apps will receive this event when users start a new assistant thread. You can listen to this event to know when a user opens the container, at which point the context will also be sent. This will contain the channel the user is currently viewing, as well as the team and enterprise IDs. It is not required to do anything with the context; in fact, some applications will have no use for it. But if you want to use it for app logic, you need to first call conversations.info to see if your app has access to the channel.

To get notifications when the user moves around Slack once the container is open, subscribe to the assistant_thread_context_changed event.
