I followed the React Simple app example and I can authenticate users using the Okta Preview app I configured. However, I want to access Groups. The docs say that I can configure it on the App page -> Sign On tab -> Groups claim. But I only see Token Credentials and SignOn Policy on that page.
Did you add the claim to the access token? This can be achieved by going API -> Authorization Server -> and selecting the default server. Within that menu, you have the ability to configure the claim’s within that Access Token and access the groups assigned to that user.
