Are there any guides for setting up data transfer between the assistants in a squad? Like if I have a resort receptionist assistant who is asking for the name and room number, and the call is transferred to the restaurant receptionist assistant, I want the name and room number readily available for the restaurant receptionist assistant so it can greet the customer saying "Hey Mr. XYZ, are you planning on dining at our restaurant or would you like to order in for your room no. 123?" Is it possible internally within VAPI's UI? Or do I have to implement this using a python code updating the API? Or is it a job for Make.com? I would really appreciate any help regarding this!
