Display minuten from TimeStamp (React, TimeStamp, Firestore)

I got issue with render correct format for Firestore TimeStamp.

I got date:

<p>{data.visitAt.toString()}<p>

value has format: Timestamp(seconds=1608276600, nanoseconds=0)

Next I did:

render(){

        const optionsdate = {
            year: "numeric",
            month: "long",
            day: "numeric",
            hour: "numeric",
            minutes: "numeric"
        };

return(
   <div>
     <label>{data.visitAt.toDate().toLocaleDateString("en", optionsdate)}&nbsp;</label>
   </div>
)

But I’m getting only:

December 18, 2020, 8 AM 

How to display minutes as well? (minuten not working)

{new Intl.DateTimeFormat("en-US", options).format(data.visitAt.toDate())}

export default function App() {
  const options = {
    year: "numeric",
    month: "numeric",
    day: "numeric",
    hour: "numeric",
    minute: "numeric",
    second: "numeric"
  };
  return (
    <div className="App">
      <h1>Hello CodeSandbox</h1>
      {/* 3/31/2020, 1:11:51 PM */}
      <h2>{new Intl.DateTimeFormat("en-US", options).format(1585640511000)}</h2>
    </div>
  );
}
