Using xlsx style to export files, the password protection does not take effect

[luokaixi]

ws['!protect'] = {
  password: '1234as',
  selectLockedCells: true,
  selectUnlockedCells: true
}
XLSX.utils.book_append_sheet(wb, ws, item.sheetName)
const wbOut = XLSXS.write(wb, {
  bookType: 'xlsx',
  type: 'binary'
})

When I export an Excel file using xlsx style and open it, the password I set does not take effect，Could you please take a look
