How do I change the navbar in a subdirectory?

Description

I want to have a German and an English version of my website. For this I put the German content .qmd file in the root directory and the english ones in an en/ subfolder. I would like the navbar to be displayed in the same language as the document that is currently open. After reading the Project Basics page in the documentation, I thought this could be done by adding a _metadata.yml file to the en/ subdirectory, where the navbar is overwritten. So I have the file _quarto.yml in the root directory:

project:
  type: website

website:
  title: "Daniel Strenger"
  site-url: "https://danielstrenger.github.io"
  navbar:
      left:
        - text: "Über mich"
          href: about.qmd
      right:
        - icon: globe
          menu:
            - text: Deutsch
              href: /
            - text: English
              href: /en/

and _metadata.yml in the en/ directory:

website:
  navbar:
      left:
        - text: "About"
          href: about.qmd
      right:
        - icon: globe
          menu:
            - text: Deutsch
              href: /
            - text: English
              href: /en/

But the navbar still appears in German everywhere. How can I change this? Many thanks!

As documented, website is a project level configuration thus it can only be set in _quarto.yml. (https://quarto.org/docs/websites/#config-file)
For short, use "project profiles" and conditional contents. (https://quarto.org/docs/projects/profiles.html)

Many others from the community made multilingual websites and books.

I suggest to search in issues and in discussions to see how they've done it.
