Button to go back to previous dashboard

Apps & Services HABPanel

Hi, I implemented a back button the following way:
in conf/html insert habpanel_widget_backbutton.js with the following content:

angular.module("backButton", [])
.directive("backButton", ["$window", function ($window) {
    return {
        restrict: "A",
        link: function (scope, elem, attrs) {
            elem.bind("click", function () {
                $window.history.back();
            });
        }
    };
}]);

Then create a custom widget with the following content:

<div style="position: absolute; top: 0; left: 0; width: 100%; height: 100%; 
                 display: flex; margin: 0; padding: 0; overflow:hidden"
     oc-lazy-load="['/static/habpanel_widget_backbutton.js']">
	<button back-button style="width: 100%; display: flex; 
                                                align-items: center;
                                                justify-content: center; 
                                                border: none;
                                                background-color: #223344;">
    <img src="../images/classic/goback.svg"></img>
  </button>
</div>

Here, the goback.svg image is placed in the folder icons/classic.
The goback.svg file has the following content:

  </g>

It works for me so far, maybe somebody finds a better way.
