嗨,我正在构建nextjs应用,我要在其中显示我正在使用google-map-react库的google地图 我有要使用红色标记图钉显示的用户当前位置,我正在用信息窗口显示所有位置,我也想显示当前用户位置。 我正在使用带有yesIWantToUseGoogleMapApiInternals为true的GoogleMapReact。 这是我的map.js文件代码

import GoogleMapReact from 'google-map-react'
import { AsYouType } from 'libphonenumber-js'
import { useState } from 'react';
import {get_location_slug} from '../utility/calculate_distance'

const phoneFormat = new AsYouType('US')
const Marker = (props,location_slug) => `
  <div class="max-w-sm rounded overflow-hidden shadow-lg">
    <div class="px-2">
      <div class="font-bold text-base mb-2 text-blue-500">
        <a href=${"/stores/"+location_slug}>
          ${props.city}
        </a>
      </div>
      <p class="text-dark-400 text-sm">${props.street}</p>
      <p class="text-dark-400 text-sm mb-2">
        ${props.city}, ${props.stateIso}, ${props.countryIso}, ${props.postalCode}
      </p>
      <p class="text-gray-700 font-medium mb-2">
        Phone: <span class="font-light">${phoneFormat.input(props.phone)}</span>
      </p>
      <p>
        <a class="text-blue-500" href="https://www.google.com/maps/dir/'+${props.defaultLat}+','+${props.defaultLng}+'/'+${props.latitude}+','+${props.longitude}+'">
        Directions
        </a>
      </p>
    </div>
  </div>
`
export default function Map(props) {
  const [locations, setLocations ] = useState(props.locations)
  const defaultProps = {
    center: {
    lat: (typeof(props.latitude) === "undefined" ? 34.850033 : props.latitude),
    lng: (typeof(props.longitude) === "undefined" ? -80.016683: props.longitude),
    },
    zoom: 7
  }

  function handleApiLoaded(map){
    let infowindow = new google.maps.InfoWindow()
    let markerCenter = 0
    props.locations.map((location) => {
     let location_slug = get_location_slug(location)
      markerCenter == 0 && map.setCenter(new google.maps.LatLng(location.latitude,location.longitude))
      markerCenter = 1
      let marker = new google.maps.Marker({position: {lat: parseFloat(location.latitude), lng: parseFloat(location.longitude)}, map: map, title: location.name})
      marker.setIcon('https://test.com/img/markers/orange.png')
      marker.addListener('click', function() {
        infowindow.close()
        infowindow.setContent(Marker(location,location_slug))
        infowindow.open(map, marker)
      })
    })
  }

  return (
    <div style={{ height: '100%', width: '100%' }}>
      <GoogleMapReact
        bootstrapURLKeys={{ key: `${process.env.GOOGLE_API_KEY}` }}
        defaultCenter={defaultProps.center}
        defaultZoom={defaultProps.zoom}
        yesIWantToUseGoogleMapApiInternals
        onGoogleApiLoaded={({ map }) => handleApiLoaded(map)}
        key={props.locations}
        />
    </div>
  )
}
I am showing all locations pins as well on my map with zoom, PLease suggest what I should add in this. Please suggest options which I can add to GoogleMapReact component to show current location as well with different marker.
