So i have two inputs from the user saved as separate variables, id like to look through my knowledge base (text where each row is a separate entity) and get each item where the data saved is in each row, i.e. search through it and find related rows, and extract a piece of info from each row that matches, I can't seem to find a way to pass the variables to the botpress ai? as ive just seen above i now know i cant use the AI task
