Hello,
Sorry about that. The guide was updated so we suggest checking this guide: https://rankmath.com/kb/how-to-redirect-www-urls-to-non-www/
You need to make sure that all your sitemap variations www, non-www, https and http will redirect to the same final variation which is https://comenta.click/sitemap_index.xml.
You can contact your hosting provider to assist you with this as well.
Also, please note that it is expected for the sitemap to have noindex as you don’t want the sitemap to get indexed on the SERP.
Please refrain from submitting your sitemap in Google’s URL Inspection tool. The correct way to submit your sitemap to Google is by following this guide: https://rankmath.com/kb/submit-sitemap-to-google/
After addressing the variation of your sitemap, please follow the steps below:
1. Flush the Sitemap cache by following this video screencast:

2. Exclude the Sitemap files of the Rank Math plugin in your caching plugin. The cache could be via a plugin or from the server. For plugins or Cloudflare, please follow this article:

3. Apply the following filter code to your site.
add_filter( 'rank_math/sitemap/enable_caching', '__return_false');
Here’s how you can add filter to your WordPress site:https://rankmath.com/kb/wordpress-hooks-actions-filters/
4. Remove all existing sitemaps from your GSC and submit only the primary one https://comenta.click/sitemap_index.xml.
If the issue persists, please share a full screenshot of the sitemap section in your GSC account containing its full report.
Looking forward to helping you.
