Formatting and styling works in a typical situation

  const workbook = new ExcelJS.Workbook();
  const worksheet = workbook.addWorksheet('My Sheet');

  // Add headers
  worksheet.addRow(["Column 1", "Column 2", "Column 3", "Column 4"]).eachCell((cell) => {
    cell.fill = {
      type: 'pattern',
      pattern: 'solid',
      fgColor: { argb: '1a5896' }, // Yellow color
    };
    cell.font = { bold: true, color: { argb: 'F8F9FA' }, }; // Make text bold
  });

However while streaming a file to a HTTP response I am unable to change styling

  const workbook = new exceljs.stream.xlsx.WorkbookWriter({stream: response});
  const worksheet = workbook.addWorksheet('My Sheet');
  
  // Add headers
  worksheet.addRow(["Column 1", "Column 2", "Column 3", "Column 4"]).eachCell((cell) => {
    cell.fill = {
      type: 'pattern',
      pattern: 'solid',
      fgColor: { argb: '1a5896' }, // Yellow color
    };
    cell.font = { bold: true, color: { argb: 'F8F9FA' }, }; // Make text bold
  });

How can I change style of cells while streaming?
