How do I change the icon on the whisker menu?

I’m customizing EOS the way I want, I already change the xfce panel icon to one that I made but I can’t find a way to change the one on the top left of the whisker menu

Also I would like to change the EOS icon on the gtk-greeter but there’s no option to change it in the greeter.conf file. I appreciate the help :slight_smile:

Right-click on it,
