Best way to update widget with AJAX

Hello,

I’m trying to find the best way to update custom Elementor widget with ajax request. I’m building dynamic widget with filters that require data being requested from server. Obviously widgets are not loaded when you request ajax-admin.php, so this leaves no possibility to add ajax request handler into widget itself. Is there proper _official_ way for widget to request data from server?

I looked through docs but I couldn’t find any information or examples.
