Is there a way to pick certain data based on a keyword in Karate?

I am working on Email Registration use case with Karate, where the user receives a registration email with a URL

I have this JSON response:

{
    "links": [
        "https://www.link1.com",
        "https://www.link2.com",
        "https://www.link3.com",
        "https://www.link4.com",
        "https://www.link5/go/there.com"
    ]
}

I would like to fetch the link which contains "/go/" in it and use it for my upcoming request as Given URL

 * def goLink = someLogic??

Apologies if this was asked or example is available. Appreciate it if anyone can redirect me to resources. What logic I can use to get URL which contains "/go/" only? Then use that as my Given URL?

Note: I tried to write a simple Java Helper class, however that didn't help either

//Java Helper
public static String fetchRegistrationURL(List<Object> myList) {
    for (Object el : myList) {
        if (el.toString().contains("go")) {
            myList.add(el);
        } else {

        }

    }
    return myList.get(0).toString();

}

Tried to pass this to feature:

* def utility = Java.type('Com.helpers.Utilities')   
* def urlList = response.links
Then print '--urlList ==> ', urlList
* def acceptURL = utility.fetchRegistrationURL(urlList)
Then print '--register ==> ', acceptURL
Then status 200

This also failed. Hoping to see if @karate has a simpler solution

Failure

Use a "filter" or "find" operation. Please read the docs: https://github.com/karatelabs/karate#json-transforms

Here is a simple example that works. You can try paste this into a Karate test and study it.

* def response =
"""
{
    "links": [
        "https://www.link1.com",
        "https://www.link2.com",
        "https://www.link3.com",
        "https://www.link4.com",
        "https://www.link5/go/there.com"
    ]
}
"""
* def filtered = response.links.filter(x => x.includes('/go/'))
* match filtered == [ 'https://www.link5/go/there.com' ]

I've used the JS Array.filter() method above, but karate.filter() can also be used. Array.find() may work better depending on your requirement.
