   * ## This is how `useMap` works:
   * This component does nothing. It's purpose is to demo `useMap`.
   * When a component is a child of `<Map>`, `useMap` has a `current` field that references the containing map.
   * See https://visgl.github.io/react-map-gl/docs/api-reference/use-map
   * See https://visgl.github.io/react-map-gl/docs/api-reference/types#mapref
   * ```
   * const maps = useMap();
   * console.log('Controls2 useMap()', maps);
   * ```
   * ### First render:
   * ```
   * {
   *     "current": {...}, // this is the same as `mymap`
   *     "mymap": {...}
   * }
   * ```
