It's not possible to change the UserId, as it is the Botpress internal ID. Altering it would result in Botpress losing the user's conversations and messages.
@astonishing-dream-61762 , I kindly ask that you refrain from using LLMs for responses. Instead, please consult the [Botpress documentation](
https://botpress.com/docs) or reach out to the AI Help Agent available on those pages for more accurate assistance
