Adding a screen option fails to show in 'All Posts' or 'Add Post' admin pages

Adding a screen option doesn't appear to be working, there's no screen option shown when I visit the 'All posts' page or 'Add Post' page. Is the below code correct and if not what should I change?

add_action(
    'wp_network_dashboard_setup',
    function() {
        add_screen_option(
            'my_custom_posts_per_page',
            array(
                'label'   = 'Custom Posts per page',
                'name'    = 'my_custom_posts_per_page',
                'default' = 2,
            )
        );
    }
);
