is there a way to get clientAddress with kafka while authentication?

Question

I'm implementing a module of authentication to kafka with the java api and i want to log clientAddress as an information.

I found AuthenticationContext that can be used with KafkaPrincipalBuilder like this:

public class CustomPrincipalBuilder implements KafkaPrincipalBuilder {
    @Override
    public KafkaPrincipal build(AuthenticationContext authenticationContext) {
        return new KafkaPrincipal("user", authenticationContext.clientAddress().getHostAddress());
    }
}

but i don't know what to pass as AuthenticationContext when invoking .build() method from the main class .

Thanks in advance,
