Get attachment link by attachment ID callback for JetEngine

attachment-link-callback.php

<?php

add_filter( 'jet-engine/listings/allowed-callbacks', 'jet_add_attachment_link_callback', 10, 2 );

function jet_add_attachment_link_callback( $callbacks ) {
	$callbacks['jet_get_attachment_file_link'] = 'Get attachment file link by ID';
	return $callbacks;
}

function jet_get_attachment_file_link( $attachment_id ) {

	$url  = wp_get_attachment_url( $attachment_id );
	$name = basename( $url );

	return sprintf( '<a href="%1$s">%2$s</a>', $url, $name );

}

Good morning, is this function able to fetch all the files of the post or just one?
