When replying to a specific message in a conversation (action comments and chat; it can co-exist with existing chat threads), show a preview of the original message directly above the reply input. This makes it clear what the user is referencing, helps maintain context in group or long-thread discussions, and improves readability. The preview should include a snippet of the message content (and optionally the sender's name), similar to how platforms like Discord, Telegram, or Slack handle replies. Clicking the preview could also navigate the user to the original message in the thread for quick context. (Random Discord examples from Google images)
