How to enable default manjaro theme?

I installed XFCE on Manjaro KDE. I’d like to know how to enable the default Manjaro XFCE theme

go to Log Out press Log Out go to the bottom and a button should be there that shows KDE’s theme icon (should be next to the power button on the logout screen) and change it to an XFCE Session wait for changes to happen and log back in and enjoy XFCE
