Get Karate request data using another util service

One of the param for my API is security related and linked to the environment on which the test would run , essentially it will be dynamic. Since this is security related, I have an internal rest API that provides this data. I want to understand what is the effective way of getting this data in Karate feature?

I have tried two different ways: 1. Defined a java util and invoke the java type and def variable for holding the data

2. Defined a Util method as part of karate-config.js

In karate-config.js

function getSomeData(someValue) {

    return Java.type('xyz.abc.util.MyUtil');
}

In the feature file defined a JS

* def dataFromJS = read('classpath:com/xyz/util/js_that_invokes_rest.js')

I want to understand if there is a pattern of how this should be done or if there is an explicit support in Karate for doing this?
