How to pass arguments to script from Windows EventLog?

Question

Windows

Good afternoon!
In the Windows security log, I bind the task to the event - Starting the program.
I specify the script (Python). Everything works fine - when the event fires, the script is launched.
How to pass arguments from the Event to the script?
In the Add arguments field, I write Event tags, but they are passed to the script as text.
Tried:
TargetUserName
-TargetUserName
$TargetUserName
$(TargetUserName)
Everything is passed as text. Can you tell me in what format it can be sent?
Thank you!
