How to get the chart instance by id , when using hooks ?

[zlobjul]

I have a graph already rendered and visible . how can I get the chart instance when using hooks ? I have a button and on click I would like to console out the instance :

<Button
                label="Export to PDF"
                size="small"
                secondary
                onClick={() => {
                  console.log(options.chart.id);
                  const chart = ApexCharts.getChartByID(options.chart.id);
                  console.log(chart); // <-- getting undefined here 
                  console.log(window.Apex._chartInstances); // <-- empty array here 
                }}
              />

...

  <Chart
          options={options}
          series={options.series}
          height="500px"
          width="99%"
          type="area"
        />

Thanks ,

having a related issue. I need to do a dynamic line chart that turns into an area graph when there is only 1 series.
