Requirements: having taken control of the conversation (section 4) — the composer only enables in HUMAN mode.
- Write your message in the text box, where “Composer disabled” used to show.
- 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.
- 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.
