Button 'myLocationButton' ionic

Does anyone know how to move the google maps ‘myLocationButton’, down to the highlighted location?

This image shows the desired location of the button.

loadMap() {
//let location = new LatLng(-34.9290, 138.6010);

this.map = new GoogleMap('map', {
  'controls': {
    'compass': true,
    'myLocationButton': true,
    'indoorPicker': true
  },
  'gestures': {
    'scroll': true,
    'tilt': true,
    'rotate': true,
    'zoom': true
  },
  'camera': {
    target: {
      lat: 43.0741904,
      lng: -89.3809802
    },
    'tilt': 30,
    'zoom': 15,
    'bearing': 50
  }
});

this.map.on(GoogleMapsEvent.MAP_READY).subscribe(() => {
  console.log('Map is ready!');
});
}
