title: Server side Blazor get bearer token
body: <p>With .net core 3.1.4, I have created a server side blazor app which uses Azure active directory
  authentication. 
  I am using following json with values pointing to my azure active directory.</p>
  
  <pre><code>{
    "AzureAd": {
      "Instance": "https://login.microsoftonline.com/",
      "Domain": "contoso.onmicrosoft.com",
      "TenantId": "e86c78e2-8bb4-4c41-aefd-918e0565a45e",
      "ClientId": "41451fa7-82d9-4673-8fa5-69eff5a761fd",
    }
  }
  </code></pre>
  
  <p>All works perfect means I can login with my Azure AD credentials but in the httpcontext's request headers, I do not get bearer access token to use for making call to my other apis further. How to get bearer access token for the logged in user in this case?</p>
  
  <p>Thanks,
  Jay</p>
