Auth0 with server side blazor ( core)

hi, i am newbie. i am using server side blazor with asp-net core. i use the Authorization Extension and i have created users, roles and groups. Now, I will secure my blazor frontend and check if the user is in a specific group. How I can do this? Thanks!

What did you do so far? Have you set up a basic authentication flow? Are you seeing the user authenticated in your app?
