You can simply set key and value for infoWindow: infoWindow.set('closed', true);

example:

const infoWindow = new google.maps.InfoWindow({
    content: 'foo',
    position: {
        lat: some_number,
        lng: some_number
    }
});

infoWindow.set('closed', true);

// Clicking on polyline for this example
// Can be marker too
polyline.addListener(
    'click',
    () => {
        if (infoWindow.get('closed')) {
            infoWindow.open(map);
            infoWindow.set('closed', false);
        } else {
            infoWindow.close();
            infoWindow.set('closed', true);
        }
    }
);
