Attribute “download” is removed

Replies: 0

Hello.
After submitting, I want to display a message with a link to download a file, but the “download” attribute is removed from the “a” tag.
I am using this code, but do not works:

add_filter( 'forminator_change_form_allowed_html', function( $allowed_html ){	
	$allowed_html = array(	
			'a' => array(
						'download' => true,
					),		
	);
	return $allowed_html;
} );
