How to setup sns notification for cloudwatch alarm using CDK for AWS Glue job

I have below code for setting up alarm for AWS glue job using CDK:

import { aws_cloudwatch as cloudwatch, aws_events as events } from 'aws-cdk-lib';

// jobName. This is our AWS Glue script to monitor
const jobFailedRule = new Rule(scope, '{DVRD replication} JobFailureRule', {
  eventPattern: {
    source: ['aws.glue'],
    detailType: ['Glue Job State Change'],
    detail: {
      state: ['FAILED', 'TIMEOUT', 'ERROR'],
      jobName: [DVRD replication],
    },
  },
})

//cloudwatch metric
const numFailedJobsMetric = new cloudwatch.Metric({
  namespace: 'AWS/Events',
  metricName: 'TriggeredRules',
  statistic: 'Sum',
  dimensionsMap: {
   RuleName: jobFailedRule.ruleName,
  },
})

//cloudwatch alarm
const numFailedJobsAlarm = new cloudwatch.Alarm(scope, '{DVRD replication} numFailedJobsAlarm', {
  metric: numFailedJobsMetric,
  threshold: 1,
  evaluationPeriods: 1,
});

Now i want to setup SNS email notification for this alarm but not sure how to do it.
