How to get SlicingProfile used from SlicingDone event?

What is the problem?
I'm trying to retrieve automatically the Slicing Profile from the event "SlicingDone"

What did you already try to solve it?
I searched in documentation but there is no "slicingprofile" payload on the SlicingDone event ;

Additional information about your setup (OctoPrint version, OctoPi version, printer, firmware, browser, operating system, ...)
OctoPrint 1.30

Hope you can help me,
