Thanks @ThomasAuzinger a lot for the contribution. We had to open a new PR with your changes because forks cannot run successfully some of our CI's jobs. For example, running the tests or documentation build leverage Github secrets to access license information. However, this is only available from the ansys organization.
Nonetheless, this PR contains your changes and they have been cherry-picked manually. You remain the author of said changes, Stefan is only the commiter (with write access to the repo).
