Exporting DynamoDB Tables Across Stacks?

The docs talk about how to share an S3 bucket across stacks but I cant seem to get it to work for DynamoDB Tables? There doesnt seem to be any “export” method.

Does this not work Universally? Is there a work-around (maybe cdk.Output)?

The new DynamoEventSource for Lambda expects a dynamodb.Table parameter. Is there some way to construct it from a table that is outside of the current stack? Or is there some alternative way to setup a DynamoEventSource?

Meanwhile I used this as a workaround to do the same thing as DynamoEventSource:

  new lambda.EventSourceMapping(this, 'DynamoDBEvent', {
    target: lambdaFunction,
    batchSize: 100,
    eventSourceArn: props.tableStreamArn,
    startingPosition: lambda.StartingPosition.Latest,
  })
  lambdaFunction.addToRolePolicy(new iam.PolicyStatement()
    .addAction('dynamodb:ListStreams')
    .addResource('*')
  )
  lambdaFunction.addToRolePolicy(new iam.PolicyStatement()
    .addActions('dynamodb:DescribeStream', 'dynamodb:GetRecords', 'dynamodb:GetShardIterator')
    .addResource(props.tableStreamArn)
  )
