@rissson yeah I didn't think of this but the bot is gonna tell us to use transifex when we update the source of truth files, not sure if we can prevent this (maybe have a ci pipeline running that extracts i18n strings and PRs them itself?)

[rissson]

Ugh, that's weird, it shouldn't have commented in this case.
https://github.com/goauthentik/authentik/blob/main/.github/workflows/translation-advice.yml#L8 this should make it skip that workflow if translation files changed and source of truth files changed as well. We probably missed something during our test of this :/

so run make i18n-extract in a CI?
