How do I add a menu item to a Pods admin menu?

To add submenu items to a specific Pod’s menu, try this:

add_submenu_page( 'pods-manage-your_pod_name', 'My submenu item page title', 'My submenu item', 'manage_options', 'pods-manage-your_pod_name-my-submenu-item', 'your_callback_function' );

Do this during the admin_menu action in WordPress, or alternatively do it during the ‘pods_admin_menu’ action.
