How to customize email subject by language in Auth email templates?

I'm using Supabase Auth email templates with multi-language support (German/English).

I can customize the email body using Auth Hooks to pass language-specific content but the subject line in Dashboard → Authentication → Email Templates only accepts a single static value.

Is there a way to dynamically set the email subject based on user language?

I used the blog below as a reference and I wonder if it is possible for the email's subject?
