Any chance to change my eclipse username?

Summary

My eclipse username is lmisingnamem8k https://accounts.eclipse.org/users/lmisingnamem8k

What is the expected correct behavior?

I have no idea how this username was generated (I think I signed the ECA on paper and it was created automatically) but would really appreciate to change it to something more meaningful e.g.

• laeubi
• laeubrich
• christoph.laeubrich
• claeubrich
• christoph
• ...

especially as it is the user-name used on gitlab as well ...
