Add a new module position for language switcher

Hi

I'm trying to add a new module position for a language switcher (with a custom HTML Module), and I don't know what's wrong.

I followed this guide: https://www.gavick.com/documentation/jo ... -position/

Step 1:

Step: 3:

How could I place this new module position in Top menu (right). The same place than Cart position?

Can you help me, please?
Thank you

This is the area that I wish to publish the language switcher and social icons module

Thanks
