In order to tell Google and other search engines which language/country version is intended for which audience, you can use a Hreflang sitemap.
A Hreflang sitemap indicate how the language/country versions are related. Each URL that has an equivalent in another language/country should be specified in a separate row of the sitemap. You need to add the URL itself with all its equivalents.
Below are some examples of how a Hreflang sitemap could look like for subdirectories, ccTLDs and subdomains.
