A storybook decorator to use React Hooks Form inside stories

story.tsx

export default {
  title: "MyComponent",
  component: MyComponent,
  decorators: [withRHF(false)], // or true to show submit button on story
} as Meta;

withRHF.tsx

import { action } from "@storybook/addon-actions";
import { StoryFnReactReturnType } from "@storybook/react/dist/client/preview/types";
import { VFC, ReactNode, FC } from "react";
import { FormProvider, useForm } from "react-hook-form";

const StorybookFormProvider: VFC<{ children: ReactNode }> = ({ children }) => {
  const methods = useForm();
  return (
    <FormProvider {...methods}>
      <form
        onSubmit={methods.handleSubmit(action("[React Hooks Form] Submit"))}
      >
        {children}
      </form>
    </FormProvider>
  );
};

export const withRHF = (showSubmitButton: boolean) => (
  Story: FC
): StoryFnReactReturnType => (
  <StorybookFormProvider>
    <Story />
    {showSubmitButton && <button type="submit">Submit</button>}
  </StorybookFormProvider>
);

How do that in sb8 or sb9?
