How can I change the url for my repository?

Someone set up a gitlab account for me but the url it produces for my repo is too long and has several hyphens - like this:
https://gitlab.com/zr-modern-machines-c-/myRepo
I want to shorten this to:
https://gitlab.com/zrmm/myRepo

Do I need to create a new account, or change the email address or what? Not sure what creates the url and whether it can be changed.
Any help appreciated.
