To define the required categories, do the following:
Navigate to Clients > Evets log > Categories, and then click +Create in the upper-right corner of the screen.
In the Caption field, enter a name that you want to apply to the category.
Click Save to create the category.
Select the category that you have just created from the categories list and click the Edit button located in the category row.
Switch to the Rights tab and enable the switches for the user groups to which you want to make this category available. Click Turn On All or Turn Off All to enable or disable the category for all user groups.
