Sending commands to Telegram bot

I have been trying to get the most basic example for a command to work with a Telegram bot, but I cannot for the life of me, figure out what I have wrong. My bot is set up correctly and I can send messages A-ok, but when I add the following lines to my automations.yaml file, nothing happens:

alias: "Telegram bot that reply pong to ping"
triggers:
  - trigger: event
    event_type: telegram_command
    event_data:
      command: "/ping"
actions:
  - action: notify.notify
    data:
      message: "pong"

This snippet of code is directly from this page. I have tried adding my Chat ID at the end in the data field, but this does not work either. What do I have wrong here?

Assuming you’re set up your notification platform as in the docs, shouldn’t that be

actions:
  - action: notify.telegram
    data:
      message: "pong"

Could be due to your notify platform isn’t setup property.

Try with this action instead:

action: telegram_bot.send_message
data:
  message: pong

These are the definitions in configuration.yaml

# Telegram Bot
telegram_bot:
  - platform: polling
    api_key: "59................_T...............hbtfv4d513P8BA"
    allowed_chat_ids:
      - 123456789
      
# Notifier
notify:
  - platform: telegram
    name: "rosamar"
    chat_id: 123456789      

This is an automation to send a notification:

alias: Notify of Home Assistant Startup
description: ""
triggers:
  - event: start
    trigger: homeassistant
conditions: []
actions:
  - action: notify.rosamar
    metadata: {}
    data:
      message: was just started
      title: Home Assistant
mode: single

Thank you all for taking some time to try to help me figure this out!

Unfortunately, none of those suggestions seem to work. I think the issue may lie within the trigger, as I made a test automation that sends messages just fine (on a time based trigger).

EDIT: I figured it out! I needed to add in quotation marks for the command in the web gui view. After I did that, the bot then recognized ‘/ping’ as a command.
