Annotations not showing on RadialBar

[NachoSanchez]

Hello i'm trying to show a small annotation on a dinamic percentage of the radialBar/gauge chart. It does not show up. I allready checked the docs back and forth this is my code so far.

const Clicks: React.FC = ({ statsResume, stats }) => {
const chartOptions = useChartOptions(statsResume);

return (

            <Chart
                height={220}
                series={[
                    60
                ]}
                type="radialBar"
                options={chartOptions}
            />
  
);

}

export default Clicks;

function useChartOptions(): ApexOptions {

const targetPercentage = 50; // Porcentaje en el que se mostrará el puntero

return {
    chart: {
        background: 'transparent'
    },

    colors: [
        "blue"
    ],

    dataLabels: {
        enabled: false,
    },

    labels: ["Clicks"],

    legend: { show: false },

    plotOptions: {
        radialBar: {
            startAngle: -105,
            endAngle: 105,
            hollow: {
                margin: 16,
                size: "70%"
            },
            dataLabels: {
                name: {
                    show: false,
                },
                value: {
                    show: false
                }
            }
        }
    },

    stroke: {
        lineCap: "round",
    },


    tooltip: {
        fillSeriesColor: false
    },

    annotations: {
        points: [
            {
                x: targetPercentage, 
                y: targetPercentage,
                seriesIndex: 0,
                marker: {
                    size: 16,
                    fillColor: '#333',
                    strokeColor: '#333',
                    radius: 8,
                    shape: "square",
                    offsetX: 0,
                    offsetY: 0,
                }
            } 
        ]
    }
};

}

and this is the result
