I can't see my contacts list/ address book other than through a compose message window

I can only see my address book when I open the address book link on compose message screen. The only other way I found I could access is to go to Contacts.Zoho.com

Why can't Zoho contacts or address book be accessible on the desktop or business.zoho.com main screen? Even when I add the application on the settings it doesn't show in the list?

Best,
Gaurav
