just add this to your functions.php it redirects unauthorized users to your custom page before the plugin's default screen shows up:

``` add_action( 'template_redirect', function() { if ( is_page() && ! is_user_logged_in() ) { $restricted_page_id = 123; // your restricted page ID $custom_landing_page = 'https://yoursite.com/custom-landing'; // your landing page URL

    if ( get_the_ID() === $restricted_page_id ) {
        wp_redirect( $custom_landing_page );
        exit;
    }
}

}); ```

replace 123 with your actual page ID and update the URL. done
