title: MS Teams: send message to private chat programmatically
body: <p>I try to find a way to send a private message in MS Teams' personal chattings.</p>
  
  <p>I know that in 'channel > connector', I can use a webhook to achieve this.
  Unfortunately, I can not find anything like that in personal chattings.</p>
  
  <p>The only thing related I find is MS Graph API, but it's not what I looking for.</p>

  <p>Currently, I am trying to use emailing API as the alternative</p>
