how to replace standard icons

The new font-icon handling leads to one question about replacing standard icons.
The old method works if we want to replace font-icons by different font-icons:

function avia_replace_default_icons($icons){
	$icons['standard'] =  array( 'font' =>'custom-font', 'icon' => 'ue807');
		return $icons;
	}
add_filter('avf_default_icons','avia_replace_default_icons', 10, 1);

now we got that SVG Iconset: Wp Media Library (svg_wp-media-library)
how to replace the standard icon by a media library svg ?

Edit i tested it with the icon name – but that does not work.
we now have to use the svg ID to replace:

function avia_replace_default_icons($icons){
	$icons['svg__standard'] =  array( 'font' =>'svg_wp-media-library', 'icon' => '40720');
		return $icons;
	}
add_filter('avf_default_icons','avia_replace_default_icons', 10, 1);
