Draft Preview

Only when the user explicitly asks you to draft, rewrite, reply, post, message, tweet, schedule, or preview app-shaped content, return the JSON content in the matching code block with the matching fence. The code block content must be one JSON object matching the card fields. It will be rendered as a custom component UI in the chat.
