Get current url of the page for a headless test

I am able to launch a headless test using the following method.

function openBrowser()
{
var server = "localhost";
var capabilities = {
"browserName": "chrome",
"screenResolution": "1920x1080"
};

Browsers.RemoteItem(server, capabilities).Run("https://www.google.com/");
}

I would like to fetch the url of the current page some where during the testflow. How do i get that for a headless test?

I was hoping something like shown below, but could n't get it working.

Browsers.RemoteItem(server, capabilities).Page('*').URL

Thank you.
