title: How to send message followed by start to a bot by link using telethon?
body: <p>I want to interact with a bot which takes chat id and message id and replies based on the message of that chat id.</p>
  <p>Usually I interact with the bot in a group chat using <code>KeyboardButtonUrl</code> having link (e.g. here is that url behind KeyboardButtonUrl, <code>https://t.me/SomeBot?start=-1001234567890_654321</code>) to the bot with data. I click on the button which directly opens the chat with bot &amp; clicking on Start button, sends the command to the bot (I think bot fetches the message from the passed data having chat id and message id) .</p>
  <p>Sending message '-1001234567890_654321' using <code>send_message</code> function doesn't work as expected.
  How can I achieve this using telethon ?</p>
  <p>Also After searching in <a href="https://docs.telethon.dev/en/latest/index.html" rel="nofollow noreferrer">telethon docs</a>, I could not find any function which returns a particular message after taking message id and chat id. <code>get_messages</code> &amp; <code>iter_messages</code> returns specified no. of last msgs only.</p>
