We are utilizing the AI Conversation Chatbot and have encountered that if a customer messages "cancel" it will opt them out/unsubscribe them from SMS rather than solely cancelling their appointment (see second screenshot). We are a bit concerned with this as unless they know to opt back in/resubscribe, we will not be able to message them to confirm their appointment was cancelled, reschedule, or communicate with the customer in any way. I spoke to HL Support who indicated that the phone carrier is the one who establishes the key words, and was curious if it can be discussed with them to modify they key words and remove "cancel" since it is interfering with a pretty common use of cancelling an appointment, but keep the other key words.
