title: How do I send a message to Telegram that includes a button that prompts the user to forward the message?
body: <p>Many Telegram bots (e.g., @youtube) have a button you can click on to forward messages sent by the bot. When the user clicks on this button, Telegram opens a contact list that lets the user choose who to forward the message to.</p>
  
  <p>How can I send a button like this? The closest thing I can find is <a href="https://core.telegram.org/bots/api#forwardmessage" rel="noreferrer">forwardMessage</a> but that expects <code>chat_id</code> target ID as a required parameter. But I won't have this target ID until the user selects who they want to forward to.</p>
