[Closed] Sitemap issue

Background of the issue:
I am working on a site under development and want to consolidate all language pages into a single sitemap instead of using separate directories for each language. Currently, our sitemaps are structured by language-specific directories, such as English: hidden link, Spanish: hidden link, French: hidden link, and Italian: hidden link. We would like to merge all translated pages into a single sitemap (e.g., hidden link), without duplicate entries. Each translated page should appear only once in the consolidated sitemap.

Symptoms:
No specific error message mentioned, but the issue is the current structure of language-specific sitemaps.

Questions:
Can we consolidate all language pages into a single sitemap instead of using separate directories for each language?
Please provide detailed steps to set this up.
