Once an appointment has been booked and approved, if you've activated the opt-in setting, it will be added to a pre-designated calendar. The calendar it's added to is the one you selected within your event level settings.
However, if you want to view a list of upcoming meetings without checking your externally connected calendars, that can be done simply by clicking on the bookings tab. Your account's bookings tab is located right underneath the event types tab. Once you've selected this tab, a new page will open with a list of your upcoming meetings.
