Cannot use an EBS alias as environmentEndpoint

[dato0011]

Creating Route53 Alias record having Beanstalk environment as a target results in the following error:

Cannot use an EBS alias as `environmentEndpoint`. You must find your EBS environment endpoint via the AWS console. See the Elastic Beanstalk developer guide: https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/customdomains.html

Here's the code:

        const aliasRecord = new route53.ARecord(this, `${config.companyName}-eb-alias`, {
            target: route53.RecordTarget.fromAlias(
                new targets.ElasticBeanstalkEnvironmentEndpointTarget(this.ebEnvironment.attrEndpointUrl)),
            zone: hostedZone,
            recordName: `${config.companyName}-alias`,
        });

    aliasRecord.node.addDependency(this.ebEnvironment);

It seems CDK doesn't support CfnEnvironment.attrEndpointUrl token as the target for ARecord. Since I can't acquire Beanstalk endpoint URL via CDK, I will need to rely on AWS API. I'm thinking to query Beanstalk through AWS API after the resource is provisioned and pass string value to ARecord instead of attrEndpointUrl token. There is a problem though, how do I get notified when a particular resource is provisioned? Is there any way to do that in CDK? I can not rely on addDependency function as I'm not trying to define dependency between resources, but execute custom code right after the resource is created.

Thanks
