How to change WebIDE/Editor commit user name?

How can I change the name that is being used for making commits using the WebIDE or the Editor via the GitLab webinterface?

By default it seems like the Name (Fullname) or a user is being used, e.g “John Doe”.

I would like to change that globally so the GitLab username is used, e.g. jdoe.

Is there a way to configure this?


Or is it really just not possible?
