Win-Kex as root via Windows Terminal?

Hi there,

i added a new Tab / Configuration in Windows Terminal to start Kali Win-Kex directly from there, as described here in seamless mode: Win-KeX | Kali Linux Documentation
It all works fine, but it start Kali with my normal user, but i want to run it with the root user. How can i do this via the Windows Terminal command? Or is it not possible?

thanks a lot
