If you are using pro version of the theme then go to Appearance >> Widget >> Here you can see header widget so you can add the multilanguage widget here and it will displayed on the top header.

This is the link.
I’ve activated multilanguage widget in the sidebars and in the footer1, but is visible only in the footer.
I’d like to put it near the social’s icons.
