Appointment reminder vs Push Notifications


How can I close an appointment reminder? When I close the push notification in macOS, the appointment reminder on the Exchange server is still active, i.e. the appointment is not closed by me. I have no way to close the appointment.

Is there no separate and additional window like in Outlook where all the appointments appear when they are due (and can be moved if necessary)?

I 've got the same problem and I post a message in this forum, but not answers yet.
