Slide toggle Jquery UI

Question

I've been looking for ways to make an enqueue of the right library of jquery ui but i dont see there is one for that, any ideas of how to use this without getting error?

        jQuery('#menu_desktop').toggle("slide", {direction: "left"});

https://developer.wordpress.org/reference/functions/wp_enqueue_script/

My jquery ui enqueue

wp_enqueue_script('jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js', '1', true);

wp_enqueue_script('menu_script', get_stylesheet_directory_uri() . '/js/menu.js', array('jquery', 'jquery-ui'), '1', true);

My error

jquery.min.js?ver=3.4.1:2 Uncaught TypeError: k.easing[this.easing] is not a function
    at init.run (jquery.min.js?ver=3.4.1:2)
    at u (jquery.min.js?ver=3.4.1:2)
    at Function.k.fx.tick (jquery.min.js?ver=3.4.1:2)
    at lt (jquery.min.js?ver=3.4.1:2)

Libraries are being imported

As jQuery UI is included in the Wordpress Core, you don't need to load it from the CDN. Please try to change your wp_enqueue_scripts from

wp_enqueue_script('jquery-ui', 'http://ajax.googleapis.com/ajax/libs/jqueryui/1.12.1/jquery-ui.min.js', '1', true);
wp_enqueue_script('menu_script', get_stylesheet_directory_uri() . '/js/menu.js', array('jquery', 'jquery-ui'), '1', true);

to

wp_enqueue_script('jquery-ui-core');
wp_enqueue_script('jquery-effects-slide');
wp_enqueue_script('menu_script', get_stylesheet_directory_uri() . '/js/menu.js', array('jquery', 'jquery-ui-core','jquery-effects-slide'), '1', true);

Also be sure to call for the Slide Effect within a document.ready function ;)
