Summary:We added the new team_chat.app_mention webhook event. The event triggers when a user mentions a specific app in a chat channel. For example, once a chatbot is added to a channel, users can interact with it by tagging it in the chat window. This enables a more conversational experience and makes the interaction visible to everyone in the channel. We added new fields (callback_url, event_ts, callback_token) to the interactive message events to provide additional information.
