How to use the @mapbox/mapbox-gl-draw/src/constants.modes function in @mapbox/mapbox-gl-draw

FreeDraw.onMouseUp = function (state, e){
    if (state.dragMoving) {
        var tolerance = (3 / ((this.map.getZoom()-4) * 150)) - 0.001 // https://www.desmos.com/calculator/b3zi8jqskw
        simplify(state.polygon, {
            mutate: true,
            tolerance: tolerance,
            highQuality: true
        });
            
        this.fireUpdate();
        this.changeMode(Constants.modes.SIMPLE_SELECT, { featureIds: [state.polygon.id] });
    }
}

CircleMode.clickAnywhere = function(state, e) {
  if (state.currentVertexPosition === 0) {
    state.currentVertexPosition++;
    const center = [e.lngLat.lng, e.lngLat.lat];
    const circleFeature = circle(center, state.initialRadiusInKm);
    state.polygon.incomingCoords(circleFeature.geometry.coordinates);
    state.polygon.properties.center = center;
    state.polygon.properties.radiusInKm = state.initialRadiusInKm;
  }
  return this.changeMode(Constants.modes.SIMPLE_SELECT, { featureIds: [state.polygon.id] });
};
