How do you utilize the google maps elevation service as a jsx tag?

Question

I have been developing a customized google map, and a feature that I need is to be able to tell about the elevation of different locations on click. I have coded the map with a bunch of jsx tags (i.e a tag for google map, a tag for marker, etc...). However, I have not been able to figure out how to do this for the elevation service. So my question is, is it possible to use the google map elevation service as a jsx tag, and if so, what is the import? If not, what are some alternatives to adding this feature?

You can check first the Elevation Service of Google Maps Platform.

You can also check how I implemented it in a reactjs code in this working sample and code snippet below:

import React, { Component } from "react";
import { render } from "react-dom";
import Map from "./Map";
import "./style.css";

class App extends Component {
  render() {
    return (
      <Map
        id="myMap"
        options={{
          center: { lat: 41.0082, lng: 28.9784 },
          zoom: 8,
          mapTypeId: "terrain"
        }}
        onMapLoad={map => {
          const elevator = new google.maps.ElevationService();
          const infowindow = new google.maps.InfoWindow({});
          infowindow.open(map);
          // Add a listener for the click event. Display the elevation for the LatLng of
          // the click inside the infowindow.
          map.addListener("click", event => {
            displayLocationElevation(event.latLng, elevator, infowindow);
          });

          function displayLocationElevation(location, elevator, infowindow) {
            // Initiate the location request
            elevator.getElevationForLocations(
              {
                locations: [location]
              },
              (results, status) => {
                infowindow.setPosition(location);

                if (status === "OK") {
                  // Retrieve the first result
                  if (results[0]) {
                    // Open the infowindow indicating the elevation at the clicked position.
                    infowindow.setContent(
                      "The elevation at this point <br>is " +
                        results[0].elevation +
                        " meters."
                    );
                  } else {
                    infowindow.setContent("No results found");
                  }
                } else {
                  infowindow.setContent(
                    "Elevation service failed due to: " + status
                  );
                }
              }
            );
          }
        }}
      />
    );
  }
}

export default App;
