I hope I'm blind, but I cannot find a common feature of ZD1 and ZCS. I am trying to add a link to a shared calendar on the ZCS. When I do a right click on the (Z) symbol, the only thing I can do is creating a new calendar within my account. Where is that hidden?

Adding a link within the ZCS web GUI still works and that one also appears on ZD2.

Thanks for help
