Can we directly just deleted it? That shouldn't be coming from an api call, so I don't think there is any need to fetch the filter, verify if the filter matches the streamId before deleting it

    public void handleStreamDeleted(StreamDeletedEvent streamDeletedEvent) {
        collection.deleteOne(Filters.eq(FIELD_STREAM_ID, streamDeletedEvent.streamId()));

    }

Good point. Except, there can be more than one rule per stream. We should call deleteMany instead.
