Scale nm-applet icon XFCE

On XFCE nm-applet's icon is too small relative to other icons on the tray.
How can I solve it ?
Perhaps a way to scale it via editing ~/.config/gtk-3.0/gtk.css may be working. But I don’t know the ID of nm-applet to do so.
Here’s how tray is showing up now.

Do you have the same issue with other themes?

Right click on the panel- choose panel- then panel preferences- then Items- then Status Tray Plugin -then click the hamburger menu to the right of where Add and remove is shown.
A box will appear where you can adjust the icon size

It’s on the maximum (64px).
I want more.
