How to make graphic point fixed?

[YogeshSwami]

Hello Community,

I am facing a problem which drawing a point graphic. After drawing the graphic, it should be fixed, but I am able to click it again and drag it. How to stop it from getting dragged?

Here is how I am creating my point graphic =>

                            const a = t.results[0];

                            let graphic = new Graphic({

                                geometry: a.mapPoint,

                                symbol:  this.fillSymbol('simple-marker', '#12AD2B', '#FFFF00'),

                            });

                            this.pointsLayer.graphics.add(graphic);

                            view.map.addMany([this.pointsLayer]);

I want to get the point drawn fixed. How to do that?

Thanks in advance
