Add milliseconds to formatDuration in date-fns

I want to convert a number of milliseconds to a human readable format using date-fns and React Native.

I've managed to do the conversion: interval > duration > human readable format and is works fine all the way to seconds but milliseconds are omitted.

Current code:

 const niceFormatDuration = (intervalInMs) => {
    const milliseconds = Number.parseInt(intervalInMs % 1000, 10);
    const duration = intervalToDuration({ start: 0, end: intervalInMs });
    return formatDuration(duration);
 };

The above code is working fine, but missing milliseconds. I've added the milliseconds to the duration object with:

duration["milliseconds"] = milliseconds;

But formatDuration still only returns down to seconds.

Also tried to add a new milliseconds format to formatDuration, but a error is thrown.

{
      format: [
        "years",
        "months",
        "weeks",
        "days",
        "hours",
        "minutes",
        "seconds",
        "milliseconds", // Not working with this line
      ],
    }

Obviously I could manually add the milliseconds in the end of the string, but that looks ugly:

return `${formatDuration(duration)} ${milliseconds} ms`;
