 * Similar to `useSubscription` but delays executing the action if args is null.
 *
 * This is useful for when you want to use a subscription but the arguments are not available yet (e.g. the result of a promise).
 * A common use case is for chaining subscriptions so that the second subscription is only executed after the first one is done.
 *
 * @see [`useSubscription`](https://github.com/PrefectHQ/vue-compositions/tree/main/src/useSubscription#readme) for more details.
