Hello,
Thank you for contacting Rank Math support today and bringing your concern to our attention.
You may need to make use of our filter to add a custom URL to the sitemap. Please refer to the code below:
/**
Filter to add extra URLs to the XML sitemap by type.
*
Only runs for the first page, not on all.
*
@param string $content String content to add, defaults to empty.
*/
add_action( 'rank_math/sitemap/{$type}_content', function() {
return '<url>
<loc>https://rankmath.com/some-custom-url/</loc>
<lastmod>2020-06-10T20:20:20+00:00</lastmod>
</url>';
});
Replace {$type} with either post or page depending on if you want the URL to be included in the post or page sitemap – respectively.
You can add the filter by following this guide:

Let us know how that goes. Looking forward to helping you.
