**Requirements:** having taken control of the conversation (section 4) — the composer only enables in
HUMAN mode.

1. Write your message in the text box, where "Composer disabled" used to show.
2. Press **Enter** to send it, or **Shift+Enter** to go to a new line without sending yet — the box itself
   reminds you with its placeholder text.
3. Tap **Send** (or Enter) when ready.

**Result:** your message shows up in the thread just like the AI's, identified with your name, and the
customer receives it over their source channel (WhatsApp, Telegram or the web chat) instantly. If the
channel couldn't deliver it, the message is marked with the delivery error — the same as happens with
attachments.
