Customization wishlist-view.php

I have made a customization in wishlist-view.php and would like to have that customized file in my themes folder, so the plugin can be updated automatically. Unfortunately the script below (in functions.php) isn’t working and I am unable to get it right. Would you be so kind pointing me in the right direction? Many thanks!

add_filter( 'wc_get_template', 'nav_override_wcwl_wishlistview_template', 20, 5 );
function nav_override_wcwl_wishlistview_template( $located, $template_name, $args, $template_path, $default_path ) {
    
    if ( strpos( $template_name, 'wishlist-view.php' ) === false ) {
        return $located;
    }

    $theme_file = get_stylesheet_directory() . '/yith-woocommerce-wishlist/templates/wishlist-view.php';
    $theme_file = wp_normalize_path( $theme_file );

    if ( file_exists( $theme_file ) && is_readable( $theme_file ) ) {
        return $theme_file;
    }

    return $located;
}
