Logging User Actions and Displaying Them on WinCC Unified HMI

Additionally, I want to display these logs on a separate screen in real time. What is the recommended method to implement this in WinCC Unified Basic?

There are possibilities to generate operator messages by script. For example if the @UserName systemtag changes (login and logout) or if an operator input or operation takes place. Bye Murof
