Spy on a non-default class export constructor with Jest

Question

I'm trying to spy on a constructor that is being used in a function I'm testing. Inside my createUpdatePermission function, the following call is being made:

const command = new UpdateCommand(input)

I want to spy on this constructor and run assertions based on the input it receives.

I've tried following the official Jest doc on how to mock and spy on non-default class exports and created my test as follows:

test('Should return an updated permission object', async () => {
  const mockDynamoResult = {
    Attributes: permissionMock
  }
  jest.mock('@aws-sdk/lib-dynamodb', () => {
    return {
      UpdateCommand: jest.fn().mockImplementation()
    }
  })
  jest.spyOn(DynamoDBDocumentClient.prototype, 'send').mockResolvedValue(mockDynamoResult as never)
  await Dynamo.createUpdatePermission(permissionMock)
  expect(UpdateCommand).toHaveBeenCalled()
})

This fails on the expect(UpdateCommand).toHaveBeenCalled() assertion with:

Error: expect(received).toHaveBeenCalled()

Matcher error: received value must be a mock or spy function

Received has type:  function
Received has value: [Function UpdateCommand]

The Jest complete example has very similar code, the only difference being that the module used in their example has a default export and the one I'm using (@aws-sdk/lib-dynamodb) has not. Any ideas how to fix this?
