And I am not being snippy here - it would be nice that would be parameter for integrations where it is not clear, but when you talk about the WEB, then the langauge the user wants to see everything - including the UI, btw., - is clear from the moment the bot loads. How? The USER TELLS THE BOT. It is in the HTTP headers - accepted languages, in order. And - it is ignored 😉 That is not good UI design for the web - if my browser tells "I want content in german or english" then the translator could already translate the initial post to the user into the langauge (in the order given, that is how the standard defiens it).
