About migrating the rootmail feature to cdk

import { Rootmail } from '@mavogel/awscdk-rootmail';
import {
  App,
  Stack,
  StackProps,
  aws_route53 as r53,
} from 'aws-cdk-lib';
import { Construct } from 'constructs';

export class BoostrapStack extends Stack {
  constructor(scope: Construct, id: string, props: StackProps = {}) {
    super(scope, id, props);

    const domain = 'mycompany.test'

    const hostedZone = r53.HostedZone.fromLookup(this, 'rootmail-parent-hosted-zone', {
      domainName: domain,
    });

    new Rootmail(this, 'rootmail', {
      // 1. a domain you own, registered via Route53 in the SAME account
      domain: domain,
      // 2. so the subdomain will be aws.mycompany.test and
      subdomain: 'aws',
      // wired / delegated  automatically
      wireDNSToHostedZoneID: hostedZone.hostedZoneId,
    });
