Which function wants to know position/geolocation?

Question

I am trying to improve a website taken over by a previous agency and I can't figure out which function attempts to get the user's location, as I would like to get rid of it. The location prompt is part of the used WordPress theme as it disappears when being changed. That's why I've been checking all JS files of the theme and the browser console when loading the page for functions like geotargeting, position, location, coords, longitude, latitude, and more but I can't find a thing.

Is there a way to find out which function triggers the location request in the browser? I am looking for general hints about JS functions that ask the user for his location, other than the ones I've already tried. For reference, here's also a link to the website.

I feel like I am missing something but after hours of crawling through all the JS files I'd like to know if I've overlooked something obvious. I will be graceful for any hint.

Geolocation calls are done through the geolocation API, located at window.navigator.geolocation.

If you have a huge number of scripts and you can't search through all of them individually, you can patch window.navigator.geolocation to throw an error when it's accessed, then examine the stack trace:

Object.defineProperty(window.navigator, 'geolocation', { get() { throw new Error('Geolocation call is here') }})

(this should only be used for debugging, of course - it should not exist in production code)

Your geolocation call is in this script:

    $(window).load(function () {
        if (navigator.geolocation) {
            navigator.geolocation.getCurrentPosition(showPosition);
        } 
        
        
    });
