Amazon Document DB: How to Implement multi-document transactions

Question

When using mongo template to start a session for transaction in document db cluster.

public class DocDBService() {
@Autowired
MongoTemplate mongoTemplate;

@Autowired
MongoTransactionManager mongoTransactionManager;

public void writeAsTransaction() {
  mongoTemplate.setSessionSynchronization(SessionSynchronization.ALWAYS);
  TransactionTemplate transactionTemplate = new TransactionTemplate(mongoTransactionManager);
  transactionTemplate.execute(
      new TransactionCallbackWithoutResult() {
        @Override
        protected void doInTransactionWithoutResult(final TransactionStatus status) {
            mongoTemplate.save(new Document("abc", 1), "test");
            mongoTemplate.remove(new Document("abc", 1), "test");
        }
      }
  );
}
}

Throws error

Sessions are not supported by the MongoDB cluster to which this client is connected

Cluster URL do have replication enabled

mongodb://user:password@cluster-url/default?ssl=true&replicaSet=rs0&readPreference=secondaryPreferred

Replication config:

rs0:PRIMARY> rs.conf()
{
    "_id" : "rs0",
    "configsvr" : false,
    "protocolVersion" : 1,
    "writeConcernMajorityJournalDefault" : true,
    "members" : [

    ],

            "w" : "majority",
            "wtimeout" : 0

    }
}

The same works in local Mongo DB 3.6 with a single machine replication.

Any information on how overcome this would be helpful. thanks in advance.

DocumentDB is not MongoDB.
