GTK installed but not appearing in Setting --> Appearance

Hello,

I installed gtk2-engines-aurora and gtk2-engines-oxygen in Chimaera, but they are not appearing in Setting --> Appearance. I uninstalled them and re-installed them see if that would work, it didn't. I am not sure what else I can do.

My system info:

OS: Devuan GNU/Linux 4 (chimaera) x86_64 
Host: X401A1 1.0 
Kernel: 5.10.0-32-amd64 
DE: Xfce 4.16 
WM: Xfwm4 
WM Theme: Clearlooks-Phenix-Deepsea 
Theme: Clearlooks-Phenix-Deepsea [GTK2], Adw 
Icons: oxygen [GTK2/3]

Any help would be appreciated.
