A third-party app is the best option for syncing student appointments with the faculty advisors' Google accounts. Student Success Hub does not have a native calendar integration tool that can sync with Google Calendar5. Salesforce Scheduler is a tool that allows customers to schedule appointments with service providers, but it does not integrate with Google Calendar either6. Einstein Activity Capture is a tool that syncs emails and events between Salesforce and Gmail or Microsoft Exchange, but it does not work with Student Success Hub appointments7. Therefore, a third-party app that can connect Student Success Hub and Google Calendar is the most suitable solution. Reference:
