I found some more information [in this thread](https://discourse.slicer.org/t/scissors-segment-editor-effects-from-a-script/8348/2), and after activating the the “Logical operators” operations one-by-one, I got this list of parameters:

```auto
  Logical operators.BypassMasking:1
  Logical operators.ModifierSegmentID:Segment_11
  Logical operators.Operation:COPY
  Logical operators.Operation:UNION
  Logical operators.Operation:SUBTRACT
  Logical operators.Operation:INTERSECT
  Logical operators.Operation:INVERT
  Logical operators.Operation:CLEAR
  Logical operators.Operation:FILL

```

I will try a bit more, but for future reference, is there a documentation page with the full list of these parameters?
