I’m just getting to grips with rasa. I need to make something like a start message where I suggest choosing one of the two suggested languages for further bot responses. I saw in config.yml there is a language for llm, I understand it also needs to be changed. I also assume that for the language it will be necessary to create a slot in domain.yml and also validate it via actions. I hope for your understanding, I could not find this information in the documentation.
