My client is polling my graphql backend and will stop polling whenever a condition is met. ``` React.useEffect(() => { if (condition) { transaction.stopPolling() } }, [..., transaction, ...]) ``` The problem is that I need to invoke `stopPolling` only when there are no network request that have been launched or that are waiting to receive the result. I tried the util method `isNetworkRequestInFlight` without success. Any insight?
