Hey guys, I have fed a document into the botpress knowledge base with FAQs for a business. I am trying to make it not answer if it does not know the answer to the question from this document. However, the bot answers on its own from the knowledge base, does anyone know how to fix this? I would also be okay with having some sort of way in which I could know if the bot knew the answer to the question from its knowledge base. This could be something such as a boolean expression which would evaluate to either true or false. I could then have it print its answer using the manual version of the knowledge agent. Any help would be greatly appreciated. Thank you
