How to remove VPN logo from System

Hello professionals,

I have installed redhat 7.5, I am setting and using my own VPN and logo. But I right click on the top right power icon and see there is system installation by default "VPN" logo there. I want to remove it but I really don't know where to go. My Gnome nautilus version is: 3.22.3
I uploaded the VPN logo which I want to remove.

Any help?

Regards,

Harry
