GPS for Javascript not TypeScript

I am migrating a project to NS7+ that had broken plugins that did not support NS7. I've moved from nativescript-geolocation to @nativescript-community/gps

I'm trying to translate the TS example in to JS, I've not made the move to TS as my app is written in JS and annoyed that all examples tend to use TypeScript rather than JavaScript and the documentation is non existent.

Im setting up GPS using the following:

var gps_master = require("@nativescript-community/gps");
var gps = new gps_master();

But get an error

NativeScript encountered a fatal error: Uncaught TypeError: gps_master is not a constructor

How do I declare GPS and get location values in Javascript to pass to ui-mapbox

The issue names the package's TypeScript example, the CommonJS require shown, and ui-mapbox as the consumer. Compare the TypeScript example with that require and verify how JavaScript should declare GPS and obtain location values; done means a working JavaScript example and documentation that resolves the constructor error.
