A customer manages their field technicians in Salesforce CRM connected to Marketing Cloud. Once an appointment with a contact is scheduled for the technician through CRM, the notification message should be sent to the contact informing them about the scheduled visit date. When the notification is sent the "Confirmation sent" checkbox on the appointment record should be updated in CRM.
