GTranslate – how to setup?

Hello,
we’re using XML Sitemap plugin in our wordpress website. We also using GTranslate Business (paid) for localizations of website into another languages.

For example this is main website:
https://www.mywebsite.com

These are websites in another languages:
https://de.mywebsite.com
https://ch.mywebsite.com
etc..

How can we create sitemaps for all languages please? If I open https://ch.mywebsite.com, I see a lot of sitemaps sorted by date but everything is in english language as main website.

Thank you.
