ical > em client notifications

Ok here’s my conf :
OSX SERVER 10.8, Ical on 10.8, and lastest version of EM CLIENT.
My problème is that em client never receives notifications for calendar sharing.
I think it was supported in 5.x version of em client.
Can somebody tells me if it is working indeed ?
Thanks a lot

unfortunately, this is not possible at the moment because the notifications for calendar sharing are not supported yet.
