What is the type of an event in Fresh of Deno?

I'm using fresh on Deno. In islands, what is the type of an event like below?

export function Sample() {
  return (
    <input
      type="file"
      onChange={(e) => ...} // what is this `e`'s type???
    />
  );
}

I also want to write like here.

export function Sample() {
  const onChangeHandler = (e: ?) => { // e's type??? How can I import the type????
     ...
  }
  return (
    <input
      type="file"
      onChange={onChangeHandler} // what is this `e`'s type???
    />
  );
}

The type seems to be JSXInternal.TargetedEvent<HTMLInputElement, Event>, Is this right? How can I import this type from fresh?

export function Sample() {
  const onChangeHandler = (e: Event) => { // the answer. doesn't need any import lines.
    const input = e.target as HTMLInputElement; // use cast
    const selectedFile = input.files?.[0];
     ...
  }
  return (
    <input
      type="file"
      onChange={onChangeHandler} // what is this `e`'s type???
    />
  );
}

My code is above. This didn't need any import lines.
