Mock jwt-decode in Jest

For test purposes I need to mock jwt-decode library. I use it as follows:

const decodedToken: { exp: number } = jwt_decode(token);

And then in tests tried the following and got errors like below:

jest.mock('jwt-decode');

TypeError: Cannot read property 'exp' of undefined

jest.mock('jwt-decode', () => ({
  exp: 123,
}));

TypeError: (0 , _jwtDecode.default) is not a function
