Therapist can log in and confirm / reject appointment.

Bool Maybe

• when the appointment is made its neither confirmed or rejected
• when the appointment is booked its neither confirmed or rejected
• but it might make sense to have it as a separate menu from edit as if it is going to take a text input then that would need to be a different data type - i.e. Confirmation, confirmed Bool, Text Maybe
• it makes sense for the button to be Confirm - if it is confirm it could be changed to reject based on the appointment -feasibly there's a btn class in css and the colour could reflect tha.t.

The effect of this would be to

• [x] Return bookedBy to Nothing.
