Can I disable Acitivities from appearing in the extended menu in my Activity Pane / Social Pane

Hi Community,

In the latest trial version 1612 (8.2.1.344) (DB 8.2.1.344) online, new activities have been introduced.

I would like to know if it is possible to disable the appearance of certain activities in the menu of the social pane / acvitity pane.

Does anyone know?

Thanks, Debbie
