How can I translate messages from Registration?

Messages from Registration in Swedish are missing. I want to help translating them. But they are not available in Transifex for Nextcloud. How can I do it?

Unfortunately your requests doesn’t contain detailed information, therefore I assume that you’re referring to the 3rd-party-app “Registration” which has its own repository and mechanism for translations. Check-out the list of closed issue tickets to see how tranlation fixes have been addressed in the past.
