How to draw a polygon using hardcoded values ​​in ngMap using angle characters

Question

I need to draw a polygon on google maps using hard-coded values. I used ngMap ( https://ngmap.imtqy.com/ ) and used the ngMap graphical manager because I also want the user to draw the polygon dynamically. if I use the drawing manager, I cannot draw a polygon with hardcoded values. and one more thing if a user places a marker on a map. I need to get the coordinates. (for example: get the coordinates in the warning field or console). anyone please help me

1.

, shape name, polygon:

<shape path="{{vm.paths}}"  name="polygon" ></shape>

2. Google Maps

vm.onMapOverlayCompleted = function (e) {
    if (e.type == google.maps.drawing.OverlayType.MARKER) {
        var pos = e.overlay.getPosition();  //get marker position
        alert(pos.toString());
    }
};  

var app = angular.module('myapp', ['ngMap']);
app.controller('DrawingManagerCtrl', function () {
    var vm = this;
    vm.paths = "[[28.646359, 77.259623],[28.645153, 77.207438],[28.680098, 77.120921],[28.680098, 77.259623]]";


    vm.onMapOverlayCompleted = function (e) {
        if (e.type == google.maps.drawing.OverlayType.MARKER) {
            var pos = e.overlay.getPosition();
            alert(pos.toString());
        }
    };
});

                map-type-id="ROADMAP"
                street-view-control-options="{position: 'LEFT_CENTER'}">
            <drawing-manager on-overlaycomplete="vm.onMapOverlayCompleted()"
                             drawing-control-options="{position: 'TOP_CENTER',drawingModes:['polygon','marker']}"
                             drawingControl="true"
                             drawingMode="null"
                             rectangleOptions="{fillColor:'red'}"
                             circleOptions="{fillColor: '#FFFF00',fillOpacity: 1,strokeWeight: 5,clickable: false,zIndex: 1,editable: true}">
            </drawing-manager>


            <shape path="{{vm.paths}}"  name="polygon" ></shape>
        </ng-map>
</div>
