Providing the physicalResourceId on AwsCustomResource onUpdate / onDelete

How should a physicalResourceId be provided to AwsCustomResource onUpdate / onDelete

AwsCustomResource works well for resource creation.

But how should onUpdate and onDelete supply the physicalResourceId that was returned during the onCreate phase?

Take this example. How should the DirectoryId to be deleted be provided in the onDelete phase? I am not sure if this just isn’t documented yet, or isn’t possible. If it isn’t possible, I feel it should be, and if it isn’t possible, what should we do instead? It would definitely be a shame if there was no intent to add this as functionality, as AwsCustomResource is extremely useful.

    var adConnector = new AwsCustomResource(this, "ADConnector", {
        onCreate: {
          service: 'DirectoryService',
          action: 'connectDirectory',
          parameters: { ... },
          physicalResourceId: PhysicalResourceId.fromResponse('DirectoryId')
        },
        onDelete: {
          service: 'DirectoryService',
          action: 'deleteDirectory',
          parameters: {
            DirectoryId: ???,
          }
        }
      }
    );

PhysicalResourceIdReference should be used and can be made into a single AwsCustomResource https://docs.aws.amazon.com/cdk/api/latest/docs/custom-resources-readme.html#physical-resource-id-parameter
