The shortcode on line 30 is of a previously created Elementor Global Google Map widget in which it used the post's title for it's dynamic address which was the city name, providing a basic city map vs a real physical address if an embed had been provided.

In theory, the ACF field could be a simple address and invoke a different global map widget using that as the dynamic address source.
