Every time the plugin creates a reservation event in the linked Google Calendar, for a service which is configured as a virtual service, the plugin also creates a Google Meet link.
The link can be found:
Inside the event details in Google Calendar.
In any notification email, if the email template contains the Google Meet link placeholder (under the Reservation group).
Inside the reservation details panel (backend, for the Admin).
Inside the reservation details panel (frontend, for the Customer).
