Weglot language switcher

Site URL: https://www.frotteedimare.ch/

Hi all!

I am trying to implement a Weglot language switcher in my secondary navigation (https://www.frotteedimare.ch/, top right corner), aiming to imitate the functionality of the native Wiglot language switcher (at the bottom of the page) but having it seamlessly integrated in the existing design.

So far i have a dropdown menu (folder) with one link in it ("EN" for English). The link is working (using "#Weglot-en" as link), following the description from this site:

https://blog.weglot.com/switching-around-on-squarespace-how-to-design-your-language-button/

Whats does not work so far is getting me back to German using the folder title. I tried to put custom code into the folders navigation title, like:

<a href="#Weglot-de">DE</a>

As explained in:
https://forum.squarespace.com/topic/11723-how-do-i-link-a-folder-title-within-the-navigation-to-a-page/

This creates a link, but does not work. Am i wrong with the address of the link?
I would love not having  an additional link in the dropdown folder for the second language.
Any ideas would be much appreciated. Thanks!
