Write to disk when using maxTagsPerSitemap

[dottely-frontend]

Hello,

I want to generate an index sitemap. Everything is fine when I follow the documentation and I end up at writing SitemapGenerator::create(config('app.url'))->maxTagsPerSitemap($n)->writeToFile($this->getDisk()->path($this->getPath()));.

The problem occurs when I use Vapor. The function writeToFile() leverages file_put_contents and this is a problem. How can I use writeToDisk() when I use maxTagsPerSitemap() ?
