/**
 * This function needs be called directly (without being hooked) to prevent being overlapped by other plugin.

 * @see ultimate-dashboard/ultimate-dashboard.php
 *
 * Example case: Yoast SEO.
 * When inside ajax request, they do specific checking before adding their menu.
 * And that checking execution happens is called directly in the main scope (without being hooked).
 *
 * Other example: TablePress.
 * TablePress has some controllers such as: frontend, backend, & ajax.
 * They don't load frontend controller if it's inside admin area.
 * Even they don't load backend controller if it's inside admin area but is doing ajax.
 * Their admin page registration is inside that backend controller.
 * While we get the menu with role simulation through ajax.
 * See "run" function inside class-tablepress.php file.
 *
 * However, we still won't be able to get the menu reliably if:
 * - it is executed earlier than UDB, and they do similar stuff like Yoast SEO
 * - or, the check for DOING_AJAX constant directly instead checking for wp_doing_ajax() (like what Loco Translate does)
 * That's why we still need to save the recent menu later (see class-admin-menu-module.php).
