I Want Remove Gnome Style Power Button

Small disorders bother me a lot. There are two power buttons in ZorinOS, but I usually use the power button in ZorinOS's unique menu, but I think the Gnome style button looks ridiculous in appearance. Can I remove this button? It's not really necessary, but I'd be happy if there was a solution.

You could try this and configurate it:

No guarentee, I haven't tested it.

It works! Thank you very much.
