How to use the @turf/great-circle function in @turf/great-circle

function buildGreatCircleArc(originCoords, destinationCoords, worldMapProjection) {
  if (isEqual(originCoords, destinationCoords)) {
    return null;
  }
  const arc = greatCircle(originCoords, destinationCoords, { offset: 400, npoints: 100 });
  if (arc.geometry.type === 'MultiLineString') {
    return buildCustomArc(originCoords, destinationCoords, worldMapProjection);
  }
  const pathMaker = geoPath().projection(worldMapProjection);
  return pathMaker(arc);
}

type: 'Feature',
    properties: {},
    geometry: {
      type: 'LineString',
      coordinates: [[start.longitude, start.latitude], [end.longitude, end.latitude]],
    },
  }
  const lengthKm = length(rawFeature, { units: 'kilometers' })
  const lengthNmi = lengthKm / 1.852
  const lengthKmFormatted = lengthKm.toFixed(lengthKm > 100 ? 0 : 1)
  const lengthNmiFormatted = lengthNmi.toFixed(lengthNmi > 100 ? 0 : 1)

  const finalFeature =
    lengthKm < 100
      ? rawFeature
      : greatCircle([start.longitude, start.latitude], [end.longitude, end.latitude])

  finalFeature.properties.label = `${lengthKmFormatted}km - ${lengthNmiFormatted}nmi`
  finalFeature.properties.isNew = isNew
  return finalFeature
}
