Multilanguage is not supported

Tried a new XML Plugin. I saw, that yours does not recognize Multilanguage solutions. In my case im using Translatepress.

Your XML ouput show this url

https://www.example.com/mypost/

But real default url is

https://www.example.com/de/mypost/

Thats ok. Google is intelligent enough to follow this automatic redirection. But url´s like

https://www.example.com/en/mypost/
https://www.example.com/fr/mypost/

are completly missing.

Used the Rank Math sitemap before. There it was working.
