[SmartCrawl Pro] How to add automatically a translated page to the sitemap

I am using WPML for all translations! Using SmartCrawl for all SEO stuff. Assumed, that whenever I add a translation, it automatically added to the sitemap.
This seems not like this. Is this a normal behavior?

The normal domain is : https://www.samui-infotech.com/ and with the translation https://www.samui-infotech.com/th/
