Starship: Default prompt as root user

Current Behavior

Right now, whenever I sudo -s in order to login as the root user in my shell, the zsh theme goes back to the default (in my case arch#).
Is this behaviour usual, and either way, what could I do to fix it?
I noticed that there's a Username module in the documentation which should default to appear when with root privileges, but it doesnt't show up.
In order to fix it I, with no hopes for it to work, created a symbolic link in the /root/ directory with my .zshrc, but this doesn't seem to work.
How could I solve this?

Environment

• Starship version: 0.37.0
