I've created a custom content type in Drupal 8.9.1. Each content post automatically renders the line

Even though my Drupal system language is set to German, I cannot find a way to show a translated version of this "submitted by" text.
When I check the translations page under
/admin/config/regional/content-language I also see a correct translation for the segment ("Geschrieben von"). But there's no indicator how this is mapped to the actual English value.
I've also seen posts saying that you have to do that manually in the Node Template. But I have not found such template and guess the approach has changed after Drupal 7.
