Colections - blog/gallery - second language SLUG

Hello when I’m adding secondary language to my site and wanted to change slugs in collections(to the language), can I do it or they have to stay the same?(as primary language)

I changed Slugs from Polish to English in my blogs(because of keywords), and they don’t update in the sitemap.

Original polish description and slug

Changed english description and slug

And my google search console says sites not found in the site map…

@Pakic any suggestions?
