```ts
import * as cloudtrail from 'aws-cdk-lib/aws-cloudtrail';

declare const sourceBucket: s3.Bucket;
const sourceOutput = new codepipeline.Artifact();
const key = 'some/key.zip';
const trail = new cloudtrail.Trail(this, 'CloudTrail');
trail.addS3EventSelector([{
  bucket: sourceBucket,
  objectPrefix: key,
}], {
  readWriteType: cloudtrail.ReadWriteType.WRITE_ONLY,
});
const sourceAction = new codepipeline_actions.S3SourceAction({
  actionName: 'S3Source',
  bucketKey: key,
  bucket: sourceBucket,
  output: sourceOutput,
  trigger: codepipeline_actions.S3Trigger.EVENTS, // default: S3Trigger.POLL
});
```

- `includeManagementEvents`: boolean = true — Specifies whether the event selector includes management events for the trail.

- `readWriteType`: [ReadWriteType](/cdk/api/v2/docs/aws-cdk-lib.aws_cloudtrail.ReadWriteType.html) = ReadWriteType.All — Specifies whether to log read-only events, write-only events, or all events.
