title: Msal.js 2.2 PKCE Authorization Flow Refresh Token Missing
body: <p>I am using Msal.js 2.2 (@azure/msal-browser 2.2.0) for <a href="https://docs.microsoft.com/en-us/azure/active-directory/develop/tutorial-v2-javascript-auth-code#how-the-tutorial-app-works" rel="nofollow noreferrer">PKCE Authorization Code flow</a>, ID and Access tokens are present but no refresh token. Did I miss out anything?</p>
  <pre><code>this.msalConfig = {
                auth: {
                  clientId: this.clientid,
                  authority: this.authority, //https://login.microsoftonline.com/{tenantid}
                  navigateToLoginRequestUrl: true
                },
                cache: {
                  cacheLocation: &quot;sessionStorage&quot;,
                  storeAuthStateInCookie: false,
                }
              };
              
      this.msalApp = new PublicClientApplication(this.msalConfig);
  </code></pre>
