The plugin does not take into account the absence of an employee

Hi!
I installed your plugin, but there is no logic. For example, an employee came up and clicked start working day, and then forgot to log out and click finish. It turns out that he overworked it. Can you make sure that the working time is taken into account if the employee moves the mouse or makes clicks? For example, an employee started their working day, logged in, and the working time started from that time. He moves the mouse or clicks, types text, the timer does not stop. As soon as the worker does not update anything more than a certain number of minutes, for example, 15. The timer stops. This is necessary to keep track of the time employees work on the site.
