 When dispatching the `prefetchThunk` as shown below you will see the same exact behavior as [described here](#what-to-expect-when-you-call-the-callback).
 
 ```js title="Non-hook prefetching example"
-store.dispatch(api.internalActions.prefetchThunk(endpointName, arg, { force: false, ifOlderThan: 10 }));
+store.dispatch(api.util.prefetchThunk(endpointName, arg, { force: false, ifOlderThan: 10 }));

 You can also dispatch the query action, but you would be responsible for implementing any additional logic.
