How can I check for untranslated email templates in a multi-store Magento 2.4.7+ setup?

I’m running a multi-store Magento 2.4.7+ setup in various different foreighn languages(currently 8 store locales).

I need to send test transactional emails from my development environment (order confirmation, password reset, …) and find which email templates lack translations for specific locales.

how do i test it? thank you.
