Numbers file (Apple) not extracting charts

I am trying to extract a chart from the numbers file, but it says no chart is available.
Code snippet:
LoadOptions opts = new LoadOptions(Aspose.Cells.LoadFormat.Numbers);
var workbook = new Workbook(“numbers_excel.numbers”, opts);
foreach (var worksheet in workbook.Worksheets) {
foreach (var chart in workSheet.Charts) { }}

Please find the attached sample numbers file.
