Telegram Notification Not An Option in Node Red Service Call

notify:
  - platform: telegram
    name: telegram
    chat_id: 12345678
telegram_bot:
  - platform: broadcast
    api_key: xxxxxxxxxxxxxxxxxxxx
    allowed_chat_ids:
      - 12345678

yet when I got to call service to send a test notification, there is no “telegram_bot” option under Domain, nor is telegram available under the Notify Domain as a Service…what am I missing?
