    return $countries;
} );

This example shows how you can update the countries list to use the country code as the choice value.

add_filter( 'gform_countries', function ( $countries ) {
	$new_countries = array();

	foreach ( $countries as $country ) {
		$code                   = GF_Fields::get( 'address' )->get_country_code( $country );
		$new_countries[ $code ] = $country;

	return $new_countries;
} );
