Hi everyone,

I’ve recently migrated to the latest version of keycloak-angular and noticed that KeycloakService is now deprecated. I'm using provideKeycloak for setup, which works fine for most things — but I’m struggling with one specific use case.

Previously, in a route guard (CanActivate), I could inject KeycloakService and call login() if the user wasn't authenticated:

if (!keycloakService.isLoggedIn()) {
  keycloakService.login({ redirectUri: state.url });
  return false;
}

Now that KeycloakService is deprecated, how should I trigger the login process from a route guard?

What’s the best practice for this?
