Shared Calendar and Security Group

Hi, i’d like my Area Manager to see in the Shared Calendar, Meetings planned by Agents in his Security Group.

He’s able to see planned Meetings

but on the Calendar Module, the Area Manager can’t see anything.

As an Admin i can see them:

The Manager Role is set to Group, and the Area Manager and Agents are in the same Security Group.

What can i do?

I answer at my own question: i was searching for a functionality available in the Full Edition of Security Suite
