Live attendance tracking

I am looking for a way to track live attendance for my companies continuing education classes. It is mandatory in all state for there to be an attendance based monitoring system. All I need is to know that they are not working in the background, such as answering their emails, FB, shopping, etc. - this means that their mouse is not leaving their webinar screen - that is it. This is offered in other systems - GoTo Webinar, WebEx, others. Are their app's that I am not aware of or can this feature be added to Zoom Webinars?
