In Agent Menu tab you define access permission for functions in the left navigation panel (Configurations, Views, CMDB, Contract, Orders, Search, Knowledge base, Social Media, Billboard and Reports) and in top panel (Tags, Favorites, Chat , Calendar and CTI).
The list contains two columns: Name of the item and Permission Type. The Permission Type column contains an image icon, enable () or disable (), used to define permission for that item.
Enabling the Permission Type means user assigned to the role can access the respective item in the menu, otherwise they can’t access it (it is not visible).
