Vue.js implementation for generating multiple stopping directions on Google Maps

Question

I wrote this part of code to show directions on google maps But currently I only have the start and end positions I want to have more stops and make the route as good as possible How do I enter multiple stops? This is what I've done so far

<table>
        <tr>
          <th>Start</th>
          <th><GmapAutocomplete @place_changed="setPlace" /></th>
          <th style="width: 50%;"><button class="btn" @click="addMarker(0)">Add</button></th>
        </tr>
        <tr>
          <th>End</th>
          <th><GmapAutocomplete @place_changed="setPlace" /></th>
          <th style="width: 50%;"><button class="btn" @click="addMarker(1)">Add</button></th>
        </tr>
      </table>

Direction component

import { MapElementFactory } from "vue2-google-maps";
export default MapElementFactory({
  name: "directionsRenderer",
  ctr() {
    return window.google.maps.DirectionsRenderer;
  },
  events: [],
  mappedProps: {},
  props: {
    origin: { type: [Object, Array] },
    destination: { type: [Object, Array] },
    travelMode: { type: String },
  },
  afterCreate(directionsRenderer) {
    console.log(1)
    let directionsService = new window.google.maps.DirectionsService();
    this.$watch(
      () => [this.origin, this.destination, this.travelMode],
      () => {
        let { origin, destination, travelMode } = this;
        if (!origin || !destination || !travelMode) return;
        directionsService.route(
          {
            origin,
            destination,
            travelMode,
          },
          (response, status) => {
            if (status !== "OK") return;
            // eslint-disable-next-line no-debugger
            //debugger
            directionsRenderer.setDirections(response);
          }
        );
      }
    );
  },
});

<DirectionsRenderer
        travelMode="DRIVING"
        :origin="startLocation"
        :destination="endLocation"
      />

And my function

setPlace(place) {
      this.currentPlace = place;
    },
    addMarker(index) {
      const marker = {
        lat: this.currentPlace.geometry.location.lat(),
        lng: this.currentPlace.geometry.location.lng(),
      };
      if (index === 0) this.startLocation = marker;
      if (index === 1) this.endLocation = marker;
      this.center = marker;
      console.log(this.startLocation, this.endLocation)
    },

So so far I'm doing fine

I've had this problem before and this will help:

First, you need to add the waypoints and optimizeWaypoints keys to directionsService.route in the DirectionsRenderer.js file After that you need to bind this key to the DirectionsRenderer component in your project and you need to create an array called waypnt in the component file and add all Destination dots and
