title: MS graph API don't send codeStatus when answering to a call
body: <p>I have a bot which should answer to calls, here's <a href="https://developer.microsoft.com/en-us/graph/docs/api-reference/beta/api/call_answer" rel="nofollow noreferrer">MS doc</a> </p>
  
  <p>Actually I can Answer a call (MS Team unhook the call ) but I get no response status code or error. In documentation it mentioned that <strong>I should get a 202 accepted status code</strong> <a href="https://www.npmjs.com/package/@microsoft/microsoft-graph-client" rel="nofollow noreferrer">see here</a> ( <code>api</code> method right after initialisation):</p>
  
  <pre><code>client
      .api('/me')
      .get((err, res) =&gt; {
          console.log(res); // prints info about authenticated user
      });
  </code></pre>
  
  <p>I have tried to check res.statusCode but I get no content.
  How can I get response from MS Teams API ?</p>
