How to change VEX V5 controller ID?

Apparently we have to change our controller names to our team number for worlds. How do I do that? Our controllers are already named, but not our team number. I tried to access it through code but I can only change the brain’s name. Nothing shows up when I connect to the controller.

It’s the team number you need to set, nothing to do with the controller.
Use VEXcode, when a brain is connected you will be able to do that here.

or it will be set during inspection for you.
