Using EQS Generator : Pathing Grid

Hi , i’m trying to use Generator around pathing grid , it doesn’t seems to make sense for a few reason :
According to the documentation in C++, it says it generator grid in a path towards context.

  1. there seems to be no place to enter the context in the EQS editor
  2. bPathToItem is an option and is declared but never used.
    bool bPathToItem = PathToItem.GetValue();

Can someone briefly guide me how to do I insert data on where it’s generating pathing towards?
