How to assign a CPT icon to the dashboard

example.php

/**
 * Sets the icon for a given CPT in the dashboard's "At a Glance" section.
 * When registering a post type, adding ‘menu_icon’ => '' will result in the menu item
 * being given the class "menu-icon-<cpt-slug>".
 *
 * Note that the dashicon used in the side menu is specified in the CPT declaration directly,
 * but the dashboard icon is not.
 * @param $cpt
 * @param string $icon
