I solved the tropic by myself (and with the Help of John based on another tropics), so if someone had the same issue :

// Add a AJAX action to get attachement URL by ID in JS
add_action( 'wp_ajax_get_media_url', 'get_media_url' );
add_action( 'wp_ajax_nopriv_get_media_url', 'get_media_url' );
function get_media_url() {
	if ( isset( $_POST['att_id'] )) {
		$attachement_id = $_POST['att_id'];
		$attachement_url = wp_get_attachment_url( $attachement_id );
		echo $attachement_url;
	} else  {
		echo '#';
	}
	wp_die();
}
// JS to add the download link
function acf_gallery_download_link() {
	if ( !is_admin() ) { return; }?>
	<script type='text/javascript'>
			( function ( $ ) { $( document ).ready( function () {
				// Add download link to attachement on hover
				$('.acf-gallery-attachment').each(function(i, item){			
					var attachement_id = $(this).attr("data-id");
					var data = {
					     'action': 'get_media_url',
					     'att_id': attachement_id,
					};
					$.post(ajaxurl, data, function(response){
						var attachement_url = response;
						$(item).children(".actions").children(".acf-gallery-remove").before('<a class="acf-icon -see dark" href="'+ attachement_url +'" target="_blank" data-id="'+attachement_id+'" title="Toto">Toto</a>');					
					});				
				});
				// Add download link to gallery side data
				acf.addAction('append', function( $el ){
					var attachement_id = $el.find(".actions").children(".acf-gallery-edit").attr("data-id");
					var data = {
						'action': 'get_media_url',
						'att_id': attachement_id,
					};
					$.post(ajaxurl, data, function(response){
					     var attachement_url = response;
					     $el.find(".actions").children(".acf-gallery-edit").before('<a href="'+ attachement_url +'" target="_blank" class="acf-gallery-see" data-id="'+attachement_id+'">See</a>');					
					});		
				});
			});
		}( jQuery ) );
	</script>
<?php}
add_action( 'admin_footer', 'acf_gallery_download_link' );
