Cannot change embedded User Manual language

Nextcloud version: 24.0.6
Operating system and version: AlmaLinux 8.7
Apache or nginx version: Apache/2.4.37 (AlmaLinux)
PHP version: PHP 8.1.12

The issue you are facing:


When I go to the Nextcloud documentation on the Nextcloud website, I can choose in which language I want to see the user manual by changing the URL (english:, french:
On a side note, some time ago I could also change it via the versions menu in the bottom left but cannot seem to do it anymore.

Anyway, my problem is with the embedded version of the user manual, when I click on the “Help” section of my Nextcloud Server install. I can’t change the language, it is only available in english and when I check the “core/doc/user/contents.html” file, at the place where the languages are supposed to be, there only is this comment: <!--Here goes the Langs-->.

Is there a way to change the language of the included user manual? If yes, is there a guide somewhere? If no, is it a planned / WIP feature?
