title: Add claims in Microsoft Identity WebApp Authentication
body: <p>I am trying to follow azure-samples specifically to sign-in users from my asp.net core 3.1 mvc app. The sample is available and documented <a href="https://github.com/Azure-Samples/active-directory-aspnetcore-webapp-openidconnect-v2/tree/master/1-WebApp-OIDC/1-1-MyOrg" rel="nofollow noreferrer">here</a>.</p>
  <p>However, I couldn't find a way to add/modify claims I received in the token. The extension method used is <code>AddMicrosoftIdentityWebAppAuthentication()</code> from <code>Microsoft.Identity.Web</code> nuget package version <code>0.4.0-preview</code>.</p>
