How to remove the WorkList LinkToAction in ESS CATS

Hi all:

In ESS CATS WorkingTime task, there is 2 links in top of this task.

One is Calendar, another one is WorkList, they are all LinkToAction.

I want to hide the WorkList in UI, but I cannot find in which view this WorkList is defined ?

Is it defined in CAP ? How to find this CAP and how to remove this link ?

Anybody can give some help ?
