Mega Menu Javascript not loading in Popup

I have got the same problem like https://ww.wp.xz.cn/support/topic/max-mega-menu-issue-with-pop-up/ and would appreciate any help, because the js-snipped is not fixing it for me.

When scrolling down and clicking the menu icon in the sticky navbar, my links are coming in without the submenus. There is no submenu when hovering any link.

I inserted the js directly in my head:

<script>
	jQuery(document).ready(function( $ ) {
	
    jQuery('.custom-js a.elementor-icon').on('click', function() {

        console.log('menu button clicked, wait 500ms');
        
        setTimeout(function(){ 
            console.log('reinit mmm');
            jQuery('.mega-menu').maxmegamenu(); 
        }, 500);
         
    } );
});</script>

Any help would be greatly appreciated.

Kind regards,
L
