Disable "name Surname" nick when logging from FAS

Hi.
It there a way, to tell Matrix server to not display my name and surname, when I’m logging from FAS? I still want to have my full credentials tied to Fedora Account, but did not expected them to land on public chat and IRC the moment I logged to matrix for the first time.

thanks

Sure, after you login for the first time, you can edit your user by clicking the icon with your initial, and go to settings.

Thanks. Good enough.
