Type '{ dateStyle: string; }' has no properties in common with type 'DateTimeFormatOptions'.ts(2559)

[TheoMer]

"typescript": "^4.0.3"

How do I resolve the above mentioned typescript error I'm receiving on the following code?:

components/OrderListItem.tsx

const newedate = (_date) => {
  const options = {dateStyle: 'medium'}; //{ weekday: 'long', hour: 'numeric'};
  const dateT = new Intl.DateTimeFormat('en-UK', options).format(_date);
  return dateT;
}

dateStyle isn't a recognized property in our lib file yet; we should add it

Any progress on integrating these properties into TypeScript?
