function register_omaha_menu() {
    register_nav_menu('omahamenu',__( 'Omaha Menu' ));
}
 
add_action( 'init', 'register_omaha_menu' );
 
add_action( 'wp_footer', 'get_link_to_pages' );
function get_link_to_pages()
{
    wp_nav_menu(array( 'menu' => 'omahamenu') ); // THIS IS WORKING. OUTPUT: Omaha Menu
    wp_nav_menu('omahamenu); // THIS IS WORKING. OUTPUT: Omaha Menu
    $menu = wp_get_nav_menu_items('Omaha Menu'); // NOT WORKING. Why? OUTPUT: false
    var_dump($menu); // NOT WORKING. Why? OUTPUT: false
    var_dump(wp_get_nav_menu_items('omahamenu')); // NOT WORKING. Why? OUTPUT: false
}

I want to get an array with the Omaha Menu. How to do that?
