Multilingual website - language switcher - URL Mapping

Hello!

I'm building a multilingual website (5 languages) using the following two tutorials.

https://www.bradgood.net/articles/multi-language-content-on-any-squarespace-template

https://www.bradgood.net/articles/multi-language-squarespace-site-with-url-mapping

I got almost all of it working, except the language switcher, which I placed in the footer. So when I'm on the English biography page and I click "Français" it should send me to the French biography page. I think I don't fully understand the second tutorial. Do I need to list all pages here? And how do I adapt it to five languages?

This is the code that I put directly in the footer (with a Code element) - maybe the issue is here? I'm not sure which link I should put here actually, I don't have a "home" page.

<div class="language"><a href="/en/" class="lang-en">English</a>  |  <a href="/nl/" class="lang-nl">Nederlands</a>  |  <a href="/fr/" class="lang-fr">Français</a>  |  <a href="/de/" class="lang-de">Deutsch</a>  |  <a href="/es/" class="lang-es">Español</a></div>

So this is how I solved it so far (Advanced > Code Injection) to at least make it work but it's of course way too long and ugly 😅
