How does the prop `store` work in react-redux Provider?

Question

In this tutorial , the author exports the below code and passes the entire called function, which returns an object, to the store prop in Provider . How does the runSaga part get ran? I don't see this in the docs.

const configureStore = () => {
  const sagaMiddleware = createSagaMiddleware(); 
  return {
    ...createStore(rootReducer,
      applyMiddleware(sagaMiddleware)),
    runSaga: sagaMiddleware.run(rootSaga)
  };
};

The example explicitly calls the function runSaga
