Hi there, I have a few more questions 1) Does the platform support having knowledge bases that allow us to share informative, guidance, and educational content/information with clients or staff members? 2) Is it possible to have staff with different domain email addresses? We have external contractors who help us. 3) Is the appointment solution only for clients and staff, or can it be shared with the public for booking? 4) Is it possible to have paid appointment sessions for clients or external people?
