How to use the aws-lambda-graphql.DynamoDBEventProcessor function in aws-lambda-graphql

(rootValue: Message, args: { type: null | MessageType }) => {
          // this can be async too :)
          if (args.type == null) {
            return true;
          }

          return args.type === rootValue.type;
        },
      ),
    },
  },
};

const server = new Server({
  connectionManager,
  eventProcessor: new DynamoDBEventProcessor(),
  resolvers,
  subscriptionManager,
  typeDefs,
});

export const handleHttp = server.createHttpHandler();
export const handleWebSocket = server.createWebSocketHandler();
export const handleDynamoDBStream = server.createEventHandler();
