Hello,

I’ve localized my entire Shopify storefront using the GraphQL API. It works pretty well but there is one thing left that I can’t seem to localize. If a customer creates an account I can’t set the locale to send their notification emails. So a german customer receives his emails in english. I can’t add the locale in the mutation query and

@inContext(language: $locale)

also doesn’t work.
