Accessing Calendar by a tab in Zoho CRM

Accessing Calendar by a tab in Zoho CRM

Hello,

Is the calendar (displaying events, appointments, etc.) available to be a tab in the CRM? With all the customization available, I'm surprised I can't find this option so far. In case it's not yet an option, it is something we have come to expect as it is a common feature in every CRM we have used/tested to date.

Thanks Zoho team.
