How can I tag orders based on locale in a multilingual store?

We have a single store with different markets, domains and languages. Each market has its own domain and one language. Now we would like to tag orders based on the locale so we can differentiate between orders coming from the different local shops. When I check the shop object in console (Shopify.locale) I get the correct locale, I cannot find the corresponding variable in flow however.

Any ideas on how I can get this to work?

Hello,
When you click on “add criteria”, Click shop > domains > localization . I think that’s what you are looking for.
