title: Telethon Get Update When Contact Join Telegram
body: <p>I'm using <a href="https://github.com/LonamiWebs/Telethon" rel="nofollow noreferrer">Telethon</a> and i'm trying to implement a handler to listen events when a contact of mine joined to Telegram, but i don't find any documentation about that.</p>
  <p>I see the docs of telethon updates events <a href="https://docs.telethon.dev/en/latest/modules/events.html" rel="nofollow noreferrer">Telethon Doc - Update Events</a> but i don't find a way to filter this specific event. Right now Telegram send a push notification when any of your contact join telegram and create a chat, so i think there should be an event that marks this</p>
  <p>Can you help me?</p>
  <p>Thanks!!</p>
