How to place subdomain in the sitemap

Question

A site made this sitemap for me:

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
<script>window._wordtune_extension_installed = true;</script>
<!--  created with Free Online Sitemap Generator www.xml-sitemaps.com  -->
<url>
<loc>http://delightpen.art/</loc>
<lastmod>2023-05-30T16:29:49+00:00</lastmod>
</url>
</urlset>

But my site has a subdomain which is actually a blog and is not mentioned here:

http://contents.delightpen.art/

How should I place my blog in the sitemap?

A sitemap contains all pages, not domains. Just replicate the <url> entry like this, for every page

<urlset xmlns="http://www.sitemaps.org/schemas/sitemap/0.9" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.sitemaps.org/schemas/sitemap/0.9 http://www.sitemaps.org/schemas/sitemap/0.9/sitemap.xsd">
<script>window._wordtune_extension_installed = true;</script>

<loc>http://delightpen.art/</loc>
<lastmod>2023-05-30T16:29:49+00:00</lastmod>

</urlset>
