Scenario I have three pages namely John James and Jessica. The Jessica page ID is 666 and I want to filter it out so that it DOES NOT show in the menu. I need help with a simple code similar to the one pasted below, that will help me achieve that. I have deliberately not registered any menu location in my function.php file.

function remove_jessica_page(){
    #
    wp_nav_menu(
        array(
            'exclude'=> 666 // exclude Jessica page from  menu
        ) 
    );
}
apply_filters('wp_nav_menu_items','remove_thankyou_page');
