通过 Spring 引导链接 Keycloak 帐户

Question

I was wondering if there is a way to Link a Broker realm user to the provider through the keycloak library in spring boot.

Situation: When we log in with a user through the realm provider, keycloak identifies their existence in the broker (or creates them) and then an email is sent to the accounts link. But the way I use keycloak, I have a service responsible for creating these to customize them for the application. In other words, when a user is created through this SpringBoot service, the idea is to check the existence of the realm provider and link the user created in the broker there.

Question: Is it possible to link the broker's account with an existing one in the provider programmatically?

Additional: it is possible to add the link directly through the admin console, so there must be a way to do it programmatically.

I tried using the setSocialLinks method or the setFederatedIdentities method but it doesn't seem to work.

FederatedIdentityRepresentation federatedIdentity = new FederatedIdentityRepresentation();

federatedIdentity.setIdentityProvider(super.getProviderRealmName());
federatedIdentity.setUserId(providerUserId);
federatedIdentity.setUserName(user.getUsername());

user.setFederatedIdentities(Collections.singletonList(federatedIdentity));
                
Response brokerResult = brokerUserResource.create(user);

Well, there's an option to do it automatically already on the Authentication flow configuration
