Verint is the vendor, they track activity while logged into the network. Not all departments have this, most do not. That probably will change at some point.
Essentially it measures activity, idle and inactive time as well as time in applications. Some activities can be flagged, like people that write a book in MS Word by putting a coffee cup on their keyboard, mouse jigglers, etc. Uncertain about putting yourself in a Teams call meeting or other ways to trick the system.
Check your entitlements for Verint and if you have it, assume your clicks are being tracked in addition to network login and out activity. Again, I assume everyone will have it at some point, but you probably don’t as of now.
