Polling onSuccess in version 5

[oren-legit]

When version 5 removed the callbacks, I actually managed to make my code a lot better in most cases.
But there's a case where I can't find a solution besides useEffect:

There are specific APIs that take a long time to do something, so we send a POST and start polling on a progress service to see the progress and show it to the user.
When the task is done (the latest polling got a "success" message), we want to invalidate a specific list that is now changed because of the mutation.

What's the right thing to do here?

useEffect is fine, you could also do in the queryFn of the polling query if you want to avoid the effect
