Hello, everyone.
I need use Visu to record user operations or it is called the operation log or the audit trail.

E.g:
1、Record the user name and time of pressing the button
2、Record the user name, time, value before modification, and value after modification of the modified variable

The effect to be achieved is shown in the figure below.

I have been searching for two days and I really can't find the relevant information.

please help me!
Greatful!
