How to use the @turf/intersect.default function in @turf/intersect

var squareTasks = squares.map(square => {
    // Clip the square with the input geometry. In this way we work with a
    // smaller area..
    let workArea = intersect(adminArea, square);
    return createProcessAreaTask(workArea, poi, origins, osrm, maxTime, maxSpeed, id);
  });

			return false;
		}
	}

	return true;
}
