Getting notified that a subscription is completed

[leifriksheim]

We are using the old subscriptions-transport-ws package for the SubscriptionClient as we are running a python backend with an outdated protocol implementation. We are struggling to find a way to understand when a subscription has finished. We can see the last incoming message being:

{"type":"complete","id":"1"}

But we have no way of knowing when this message is recieved from within urql using React and the hooks. I would imagine fetching, should be set to false when complete is done, or something similar. Anyone knows how to hook into this somehow?
