Subscribe this event

First create an EventListener class in your Extension. It may look like this.

        EXT:my_extension/Classes/EventListeners/BeforePhoneAreaCodeInitializeEventListener.php
    

<?php
declare(strict_types=1);

namespace MY\MyExtension\EventListener;

use LIA\LiaForm\Event\BeforePhoneAreaCodeInitializeEvent;

final class BeforePhoneAreaCodeInitializeEventListener {

    /**
    * Set a custom area code list.
    *
    * @param BeforePhoneAreaCodeInitializeEvent $event
    * @return void
    */
    public function __invoke(BeforePhoneAreaCodeInitializeEvent $event): void
    {
        $event->setDataSourcePath('EXT:my_extension/Configuration/Data/MyAreaCodeList.json');
    }
}

Now register this EventListener in your Services.yaml.
