title: Bot Framework - Sign-In Card, how get auth result
body: <p>working with Microsoft Bot Framework V3 I started using Sign-In Cards.</p>
  
  <p>I did a simple cut and paste from example code page into my code and let's say it works (compiles):
  <a href="https://docs.botframework.com/en-us/csharp/builder/sdkreference/attachments.html" rel="noreferrer">https://docs.botframework.com/en-us/csharp/builder/sdkreference/attachments.html</a></p>
  
  <p>What was expected is a behavior similar to oauth process so to be redirected to , do it's own stuffs and return the auth resul including all informations.</p>
  
  <p>What I realized is that it simply open a new web page to the link I provided, that's all...</p>
  
  <p>No other code founded elsewere...</p>
  
  <p>So far it seems useless as I could provide the link simply with normal messages based on this behavior, also there is no communication with the bot.</p>
  
  <p>Did I missed something? </p>
