gave it a spin, but it is not good, overall
it works to receive the input only, but the data is not 2-side workable, eg. it is not possible to display an international phone in the element for prefilling purposes. it has also: - a bug in the front end (transparent menu when dropdown is open downwards - upwards works ok) - error is not displayed correctly (sometimes the number is smaller or bigger than the template and do not trigger it correctly) so, it is nice, but not possible to work with it, unfortunately
