As usual, when you do something really rare than it is not easy. The same applies to setting up sitemap in WordPress. There are many plugins. It is annoying to test them. Unfortunately I tested few plugins just to find out that since WordPress 5.5 it is built in functionality: https://make.wordpress.org/core/2020/07/22/new-xml-sitemaps-functionality-in-wordpress-5-5/
Finally, I don’t need to by annoyed by browsing through different plugins.
So, I don’t need plugin, which is good. You can find my sitemap here: https://angry-dev-thoughts.com/wp-sitemap.xml
