the calender app is great but I have one thing to find out. I would like to have a calender which is been use by two people. the calender should be also shared to a third person but this person should only see that there is an blocked time but not what is the appointment.
A secretary has a calender with her boss. He is a doctor. She and also the doctor can place appointments in the calender. But there is another doctor from another office, which should get the calender shared with reading rights but is not allowed to see the information of the appointments.
How can I set this up?
