Adding language selection to header menu (Divi Theme)

Hi, does anyone know how I can add the language selection widget to the header menu? I’m using Divi Theme and it doesn’t seem to allow that. The language widget can only be displayed either as a side bar or a footer and they are always vertical.

What I want is for the language selection to appear at the top right hand corner (below my header (menu) bar) and displayed as a horizontal list instead of a vertical one.

Any help would be greatly appreciated! Thank you!
