Is tx.close() necessary in Javascript?

I have read the following two pieces of documentation and I have the question, is tx.close() necessary in Javascript?
https://tinkerpop.apache.org/docs/current/reference/#gremlin-javascript-transactions https://docs.aws.amazon.com/neptune/latest/userguide/access-graph-gremlin-transactions.html

try {
  const gtx = tx.begin();

  gtx.mergeV(
          new Map([
              [t.id, 'exampleId'],
              [t.label, 'exampleLabel']
          ]))
          .option(merge.onCreate, new Map([['lastUpdatedTime', eventTimeStamp]]))
          .iterate();
           
        tx.commit();
} catch (error) {
    logger.error(error);
    // roll back the transaction
    tx.rollback();
}

try {
  const gtx = tx.begin();

  gtx.mergeV(
          new Map([
              [t.id, 'exampleId'],
              [t.label, 'exampleLabel']
          ]))
          .option(merge.onCreate, new Map([['lastUpdatedTime', eventTimeStamp]]))
          .iterate();
