Sitemap & Empty Terms

Hi,

Please provide a solution similar to this:
https://wordpress.org/support/topic/list-categories-with-no-posts-in-xml-sitemap/

AIOSEO Sitemap is not including Product Categories with 0 posts.
All our main categories have only sub-category in which products appear. For this reason, the main categories do not appear in the sitemap.xml

Following the AIOSEO documentation we did not find a solution similar to Yoast who do it knowingly.

Code-Snippet would be fine. Please provide one.

Regards;
