title: How to get new message received from the telegram channel using telethon
body: <p>I used the code given <a href="https://docs.telethon.dev/en/latest/basic/updates.html" rel="nofollow noreferrer">here</a> to receive new message from the user but it does not work when a new message arrives in the telegram channel. </p>
  
  <pre><code>@bot.on(events.NewMessage)
  async def my_event_handler(event):
      print(event.stringify())
  </code></pre>
  
  <p>Setting <code>events.NewMessage(chat='chat')</code> or <code>events.NewMessage(chat='channel')</code> didn't work.</p>
  
  <p>How can a telegram bot get new message event from a telegram channel ?</p>
