[Solved]-Exporting 2 button option issue in highchart-Highcharts

Use this

exporting: {
            buttons: {
                contextButton: {
                    menuItems: null,
                    onclick: function() {
                        this.exportChart();
                    }
                }
            }
        }

This will generate direct export button without any context menu
