How to add menu for subscriber user in wp

I want to add custom menu item in users panel in my site :http://persianvl.com

I use the following code in my plugin but don't work for me :(

add_action('user_admin_menu', 'add_users_menu');
function add_users_menu(){
add_menu_page( 'title', 'menu title', 'manage_options', 'subscriber', 'admin_menu_actions');
}

Or this code ::

add_action('admin_menu', 'add_users_menu');
function add_users_menu(){
add_menu_page( 'title', 'menu title', 'administrator',"shop_system", 'admin_menu_actions');
}

or ::

add_users_page( 'title', 'menu_title', 'subscriber', 'menu_slug', 'admin_menu_actions');
