Auto-Complete in vs-code for custom button component in react using Flow.js

[invalidtoken]

I am creating a Custom Button component in React. The basic version of the component looks something like this -

// @flow
type ButtonPropsType = {};
const Button = (props: ButtonPropsType) => {
  const { children, ...rest } = props;
  return <button {...rest}>{children}</button>
}

let App = () => {
  return (
    <div>
      <Button style={{ margin: 10 }}>Sahil Kapoor</Button>
    </div>
  )
}

How should I define the type of my Button component so that VS-Code knows that my Button component accepts all the attributes of a normal React button element like style, onClick, className etc?
Right now when I use my Button component VS-Code does not know that it accepts all button attributes and hence does not show auto-complete.

Flow doesn't type check any props passed to (lower-case) DOM elements in React. For instance, this passes type checking:

// @flow
import * as React from 'react';
const Test = () => {
  return <button style={1} onClick={{}} className={() => {}} />
}

I'm not sure what would be providing the auto-complete for these inside vs-code.
