AngularJS + Angular Google Maps (Angular-UI). How to change the style of ui-gmap-window directive?

Question

Angular

Good time.
Can anyone tell me how to style the ui-gmap-window directive (more precisely, remove the standard styles: white background, arrow, etc.)? A whole day has been spent, but to no avail at the moment.
On the main page, you need to display a map with markers and by clicking on the marker a window should be displayed (screen will be provided below). Source:

<ui-gmap-google-map center='vm.gMap.map.center' zoom='vm.gMap.map.zoom' options="vm.gMap.map.options">
            <ui-gmap-marker ng-repeat="marker in vm.markers"
                            idkey="marker.id"
                            coords="marker.position"
                            options="marker.options"
                            events="marker.events"
                            click="marker.infoWindow.showInfoWindow(vm.markers)">
                <ui-gmap-window show="marker.infoWindow.visible"
                                closeClick="marker.infoWindow.closeInfoWindow(marker)"
                                template="marker.infoWindow.template"
                                templateParameter="marker"
                                options="marker.infoWindow.options"
                                ng-cloak>
                </ui-gmap-window>
            </ui-gmap-marker>
        </ui-gmap-google-map>

The ui-gmap-window directive is important here. And here are its settings:

infoWindow: {
  visible: false,
  template: require('./templates/info-box-window-template.html'),
  showInfoWindow: function (markers) {
  // Hide all opened info window on maps
    markers.map(function (marker) {
      marker.infoWindow.visible = false;
    });

    this.visible = true;
  },
  closeInfoWindow: function () {
    this.visible = false;
  }
}

Browserify is used to build the application. The ./templates/info-box-window-template.html template is included in the template variable, the code of which is below:

<div class="infoW">
    <div class="propImg">
        <img ng-src="{{ ::parameter.image }}">
    </div>
</div>

Now, when clicking on the marker, the following window is displayed:

And the following result is needed: You

need to remove the standard styles so that you can define everything yourself. It is desirable to possibilities of the directive. There is a wrapper for such things called InfoBox, but I couldn’t attach it to the directive.
I would be very grateful if someone could help me solve this problem.
