Access user info from SecurityIdentity using quarkus-oidc

I am using quarkus-oidc with keycloak and I have the following resource

package graphql;

import io.quarkus.oidc.IdToken;
import io.quarkus.oidc.UserInfo;
import io.quarkus.security.Authenticated;
import io.quarkus.security.identity.SecurityIdentity;
import org.eclipse.microprofile.graphql.Description;
import org.eclipse.microprofile.graphql.GraphQLApi;
import org.eclipse.microprofile.graphql.Query;
import org.eclipse.microprofile.jwt.JsonWebToken;
import javax.inject.Inject;
import javax.ws.rs.core.Context;
import javax.ws.rs.core.SecurityContext;

@GraphQLApi
public class MeResource {

    @Inject
    SecurityIdentity securityIdentity;

    @Query
    @Authenticated
    public User me() {
        return new User(securityIdentity);
    }
}

My quarkus configurations is the following

quarkus.oidc.auth-server-url=http://localhost:8080/auth/realms/my-realm
quarkus.oidc.discovery-enabled=true
quarkus.oidc.client-id=my-app
quarkus.oidc.credentials.secret=**********
quarkus.oidc.enabled=true
quarkus.keycloak.policy-enforcer.enable=true
quarkus.http.port=8081

I am calling the query as follow

curl --request POST \
  --url http://localhost:8081/graphql \
  --header 'authorization: bearer eyJhbGciOiJSUzI1NiIsInR5cCIgOiAiSldUIiwia2lkIiA6ICItVFJsRHlFWnB3MGRXRzd4cUZPajl6U2V6aklMTURUaFFkNl9YU0JKYzRJIn0.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.hadUk8HzFnn0njk6U5za2N568QTX5w_opR8Vs7ub-hoyAWVND3fjyQJI9mpwKEvqp_ayWHyAcHoGAM16FXnjXKZqNl-iTbpgKNgV9-eMqU7NbR9UokZgGVUUs15cMANlihPiBm7919oG9zkzetNoo7h3ouXwQJwx5nLTIvDJAT-sCgUR5uygY_fEd5W6Jl8Z6kmzrAXKPJP2XSu3pMG0QdWT9Zz0IlW_g91H8bfY0g5OO4cgSuC5pZSu4UiLSKiGK45z_Y-7J-rosItYhIYiJ8v__ZeTeribpKbt14RfuvgVYpqbb6uAgYQkF6ho6sQMhg69sY6RieMG9jM07xCufw' \

The content of the jwt is

}

How can I access the user info stored in the token using quarkus oidc? I' have seen that there is an option quarkus.oidc.authentication.user-info-required=true which will be calling the keycloak user-info endpoint to resolve the info from the token but it seems it is only working for opaque tokens which keycloak does not provide!

I'm not an expert on Quarkus, but following the guide for using OpenID it seems that you should inject the JsonWebToken jwt to be able to retrieve all the information related to a particular request authenticated via keycloak.

Later you can ask for any of the data included in the token. Probably you may need to ask for specific claims (in your case "family_name", "given_name", "email", etc) using the previous jwt
