Minimize and maximize button in wsl

I am currently using wsl2 with Ubuntu 22.04 on Windows 11. I am not able to see minimize/maximize button on the titlebar. I first discovered this problem with sublime text, but when I tried other apps, they had the same problem. To solvw this I tried the following command:

gsettings set org.gnome.desktop.wm.preferences button-layout "close,minimize,maximize:"

This was the output:

(process:26220): dconf-WARNING **: 18:15:12.690: failed to commit changes to dconf: Could not connect: No such file or directory

My DISPLAY environment variable is also set to :0. I also, tried to fix this through the dconf-editor, but that produced the same error.

Please tell me how to fix this.Thanks.
