Sitemap multilanguage

Hello,

I am using Polylang with subdomain structure as it.example.com, english is the default language and directly under example.com
When calling the sitemap manually with the “View sitemap” link inside the XML sitemap module, it only shows me the english pages, which is correct from the point of view that the languages are kept separated because Google prefers it this way.
I just wonder if the sitemaps for the other languages are also correctly and automatically transmitted to Google?

Thanks a lot
Sofian
