You must have permission to update Meeting Links to perform the steps below.
On the Meeting Link's page, click the "Notification Settings" tab.
Click "Add Notification" in the upper-right corner.
Choose a trigger, channel, and Notification.
Click "Save".
For “Event Reminder” Notification Triggers, a parameter called "ahead by" must be set. This dictates how much time ahead the notification will be sent before the event.
Even when not specifically set within a Meeting Link, email notifications will be sent for Meeting Link Scheduled, Event Rescheduled, Event Reassigned, and Event Canceled Triggers using the default setting.
