title: How do I send a 1:1 welcome message?
body: <p>I am looking to send a welcome message when a user installs my Teams bot.</p>
  
  <p>I've looked at the Teams API documentation and have received mixed messages on whether this should be possible. I have read in various places that my bot should receive a conversationUpdate when the bot is installed, as well as reading in various issues that I will not receive such an event.</p>
  
  <p>However, a bot exists which has this functionality. Hipmunk, when installed with private scope, sends me a message without being provoked further. How is this bot able to do this, and how can I replicate this functionality?</p>
  
  <p>Thanks</p>
