I tried to add watermark to all photos but couldnt understand. Its not working at all.

 <x-curator-glider
                            class=""
                            :media="$image"
                            background=""
                            blur=""
                            border=""
                            crop=""
                            device-pixel-ratio=""
                            filter=""
                            fit=""
                            flip=""
                            format=""
                            quality=""
                            orientation=""
                            pixelate=""
                            sharpen=""
                            width=""
                            watermark-path="{{asset('img/watermark.png')}}"
                            watermark-width="200"
                            watermark-height="200"
                            watermark-x-offset="20"
                            watermark-y-offset="20"
                            watermark-padding="20"
                            watermark-position="top"
                            watermark-alpha="40"
                        />
