Use Window_handles to click button in location pop-up, with nightwatch

I have a test in nightwatch for a function that requires you to share your location in order to show some results. Everytime i interact with that button, the geoiplocation default pop-up of the browser shows up and i need to interact with it (accept or dismiss it) in order to move on with the test.

In order to do this, i have tried acceptAlert mentioned in the Nightwatch api documentation, with no success. I read in several places that in this case you can use the command to switch to the new window, like here :

browser.window_handles(function(result) {
    var handle = result.value[0];
    browser.switchWindow(handle);
});

My problem is, how do i click that button, when i cannot view source of that pop-up to get the html for it? Or is there other way i can dismiss it?
