Can I add an XML sitemap to the Atlas platform?

The XML site map is not needed, as the site will still be indexed properly. For those that would like to try adding the XML sitemap, you could try this by using a tool or manually adding it, then uploading the file via SFTP to (webui/angapp) directory. You would then have to update the meta tags to reference it, you can update meta tags by reading the following: https://www.thrinacia.com/faq/post/how-do-you-add-meta-tag-to-your-page
