@jor4science, this is not production-critical but easy to merge.

Thanks @saschaszott .
Could you collect this PR with other PR: AccountServiceImpl : resolve merge conflicts in Javadoc comments #484 , added German translations #39, add missing translation keys #28, SCSS cleanup: remove duplicated SCSS variables #107, remove console.log in ngOnInit #111 together in a single "clean-up-patch" so that is easier for us to quickly work and integrate all this PR in the next release.

@jor4science , could you clarify how this would work? The PRs affect both the Angular frontend and the Java backend.

You're right. My fault. Obviously collect Java backend:
this PR with AccountServiceImpl : resolve merge conflicts in Javadoc comments #484

I'm adding the comment on Angular added German translations #39 side.
Thanks
