	if s.cfg.operationNotifier != nil {
	s.cfg.operationNotifier.OperationFeed().Send(&feed.Event{
	Type: operation.BlockGossipReceived,
	Data: &operation.BlockGossipReceivedData{
	SignedBlock: blk,
	},
	})
	}

execution_payload_gossip mirrors block_gossip event, so you can see exactly same pattern as our implementation like above.
