When I send the booking information to Zapier using "Send to Zapier" event, the Zap runs successfully, but it doesn't trigger the "Event from Zapier" which should return back a confirmation message back to user in chat box. My Zap captures the information from Botpress using the Botpress integration (not webhook), creates an event in Google Calendar and should send the event back to Botpress. What happens when I test the conversation in chatbot, after I get the message "Your booking has been sent, please wait..." it says below "Conversation has ended".
