Failed telegram integration

Hi everyone,

I am runnning HA on VirtualBox,
Home Assistant 2022.10.1
Supervisor 2022.09.1
Operating System 9.0
Frontend 20221006.0 - latest

I installed Telegram and I am getting the following error:

As usual, I might be missing a comma or a small letter. I appreciate your feedback. Thank you

Forgot to show my setup, here we go:

telegram_bot:
  - platform: polling
    api_key: !secret telegram_bot_api_key
    allowed_chat_ids: !secret telegram_bot_chat_ids

notify:
    - platform: telegram
      name: telegram
      chat_id: !secret telegram_bot_my_chat_id
