title: how to delete a chat message which posted in telegram-cli?
body: <p>I need to delete a message that's posted in chat (private or group or super-group). Is there any command in <code>telegram-cli</code> or other telegram clients that 
  do this? If not, what should  i do?</p>
  
  <p>I only saw this command <code>delete_msg &lt;msg-id&gt;</code> in telegram-cli wiki page, but i don't know what's <code>&lt;msg-id&gt;</code>.</p>
