How to use the geolib.getRhumbLineBearing function in geolib

static calculateBearing(from: PlaneData, to: PlaneData) {
    if (!from) return 0;
    if (from.longitude === to.longitude && from.latitude === to.latitude) {
      throw new Error('No bearing');
    }
    return geolib.getRhumbLineBearing(from, to);
  }

static calculateBearing(from, to) {
    if (!from) return 0;
    if (from.longitude === to.longitude && from.latitude === to.latitude) {
      throw new Error('No bearing');
    }
