How do i use LUIS with outsystems to get intent and entities of AI chatbot question?

How do i integrate LUIS with the azure AI Chatbot in outsystems so that when I ask a question to the AI chatbot, the AI chatbot can pick out the intents and entities of the question and give answer according to the entities and intents instead of giving a wrong answer like "No QnAMaker answers found". I followed the outsystems Azure LUIS Connector guide but i don't understand and it doesn't seem to work for me.
