1test('the data is peanut butter', () => {2  expect(Promise.reject(new Error('error'))).toReject();3});4I am using jest-extended in my project and I am trying to use toReject method of jest-extended to test if a promise is rejected or not. But when I run the test, I get an error saying "TypeError: expect(...).toReject is not a function".
