How to use the @testing-library/react-hooks.act function in @testing-library/react-hooks

function checkTypesWithVoidResult() {
    act(() => {});
}

function checkTypesWithUndefinedResult() {
    act(() => undefined);
}

function checkTypesWithPromiseResult() {
    act(() => Promise.resolve());
}

function checkTypesWithVoidResult() {
  const callback = () => {}
  act(callback)
}

function checkTypesWithUndefinedResult() {
  const callback = () => undefined
  act(callback)
}

it('when validation and submit successful', async () => {
      const { result, waitForNextUpdate } = renderHook(() =>
        useForm(options)
      );

      const func: any = async () => {
        result.current.handleSubmit(event);

        await waitForNextUpdate();
      };

      await act(func);

      expect(result.current).toMatchSnapshot();
      expect(options.onSubmit).toBeCalledWith(values);
    });
