Hello, I am following this reference: "https://www.kali.org/docs/containers/kalilinux-lxc-images/" to set up GUI container for Kali. I noticed some error in the reference, but do not know how to get in touch to provide feedback and update the reference doc.

The second thing, the GUI set up seems to be working, as I can call xclock and zap proxy from the GUI container. However, I am getting error when trying to use xfce4-panel. I am not sure if this is OS or xfce4 error. Here's the error message when I run this command - "lxc exec gui-kali -- sudo -u kali xfce4-panel".

Error:
