[SOLVED] Vaadin 21 View Roles

I want to rewrite my Vaadin application to Vaadin 21. With the Vaadin starter builder (https://vaadin.com/start) I created a simple app. Currently my main struggle is to apply my simple CustomAuthenticationProvider to the Security manager to able to use the @RolesAllowed({ "user", "admin","USER"}) annotation.

Main problem that my AuthToken is generated somewhere else... Its generate somewhere an empty Granted Authrities and ignore my custom AuthProvider code.

Question: How to nicely handle role based access control?

Where I can use this annotation correctly:

@RolesAllowed({ "user", "admin","USER"})
public class ProfileView extends VerticalLayout {

Console after login:

UsernamePasswordAuthenticationToken [Principal=c.farkas, Credentials=[PROTECTED], Authenticated=false, Details=WebAuthenticationDetails [RemoteIpAddress=0:0:0:0:0:0:0:1, SessionId=DDE103F559B2F64B917753636B800564], Granted Authorities=[]]
xxx[USERcica, admin, USER]
??UsernamePasswordAuthenticationToken [Principal=c.farkas, Credentials=[PROTECTED], Authenticated=true, Details=null, Granted Authorities=[USERcica, admin, USER]]
