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?

The subject line seems to take variables but not sure if conditionals work there. You might have to test it to see if it works.
@silentworks thank u for ur response!
i did! it always falls back to the else... the content body works fine tho!
I would expect it to outright fail if it wasn't working. Maybe just output the
{{ .Data.language }} in the subject along with some text and see what it outputs.
