How to tell if an AppleScript is invoked from a KM macro?

What can I add to an AppleScript to detect whether or not it was invoked from KM? In fact, is there anything a script or a handler can do to detect how it was called?

This basic question was addressed here:

Is There Way For an AppleScript or JXA script To Obtain the Name or Id of the Macro That Is Executing The Script?

I have a lot of Macros that are Executing JXA script. Is there way for the script being executed to find out some kind of name or id of the macro that is executing the script without hard coding the name in the script? Thanks!

The answer is there is no automatic, built-in way.
The only way is to set a KM Variable before the Execute Script Action.
