How to set custom AbstractHealthIndicator as not sensitive in Spring Boot so it shows for /health endpoint?

I am running Spring Boot v1.5.2.RELEASE.

How to have /health show below without disabling security for entire Spring Boot project?

{
    "status": "UP",
    "testing": {
        "status": "UNKNOWN",
        "foo": "bar"
    }
}

Here is my code below for TestingHealthIndicator.java:

import org.springframework.boot.actuate.health.AbstractHealthIndicator;
import org.springframework.boot.actuate.health.Health.Builder;
import org.springframework.stereotype.Component;

@Component
public class TestingHealthIndicator extends AbstractHealthIndicator {

    @Override
    protected void doHealthCheck(Builder builder) throws Exception {
        builder.withDetail("foo", "bar");
    }
}

"testing" shows in /health only if i set the following in application.properties

management.security.enabled=false
management.health.defaults.enabled=false

But I do NOT want to disable security for entire project.

I did see some helpful info here: https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-endpoints.html, but did not see a specific way set custom AbstractHealthIndicator as non-sensitive.
