Crawl manual link

[omidMolaverdi]

Thanks for the great work.

I added sitemap to the website. It works great but does not crawl the manual links. Please can you advise?

 $path = base_path('../public_html/sitemap.xml');
        SitemapGenerator::create('https://www.xyxyxyx.com)'
            ->configureCrawler(function (Crawler $crawler) {
                $crawler->setMaximumDepth(3);
            })
            ->hasCrawled(function (Url $url) {
                if ($url->segment(1) === 'viewlink') {
                    return null;
                }
                return $url;
            })
            ->getSitemap()
            ->add(Url::create('/thread') <------------- I need to crawl this link and add sub links to the sitemap
                ->setChangeFrequency(Url::CHANGE_FREQUENCY_DAILY))
            ->writeToFile($path);
