Spring: @RequestScope - annotated method does not get called

Question

In the application I would like to create a request-scoped bean (annotated with @RequestScope) that would represent a user of the application (for authentication OAuth2 is used with the company's own authentication provider based off keycloak; the problem is that the Principal doesn't contain extra information about the permissions this particular user has and they have to be retrieved from another service, which is why I want to have this request-scoped bean that would retrieve fresh permissions on each request).

public class MyApplicationUser {
  private final String name;
  private final List<Permission> permissions;

  /* all-arg constructor, getters */
}

@Configuration
public class UserConfiguration {
  private final PermissionService permissionService;

  /* constructor, etc */
  @Bean
  @RequestScope
  public MyApplicationUser currentUser(@CurrentSecurityContext(expression = "authentication") OAuth2AuthenticationToken authenticationToken) {
    /* call permissionService, map the result and the token details data to MyApplicationUser instance and return it*/
  }
}

Although on each request a new instance of MyApplicationUser is created, it is not created by calling the currentUser method (it never gets called), but rather it seems that spring uses the provided constructor and supplies nulls as parameters, which is not what I want. How do I fix that?

P.S. the main class extends SpringBootServletInitializer
