Describe the bug

When upgrading from version 13 to version 14 of azure@arm-appservice, using beginCreateOrUpdateAndWait() no longer automatically triggers Delegation within the domain resource group after purchasing a custom domain. Currently, we are performing Delegation manually, but I am posting this issue because I would like to know if there have been any changes to the SDK's operation code as the version has been upgraded."

To Reproduce
Steps to reproduce the behavior:

1. Run the code below

 try {
      const { hostname } = params;
      const credential = await AzureService.login();
      const client = new WebSiteManagementClient(credential, AZURE.SUBSCRIPTION_ID);
      return client.domains.beginCreateOrUpdateAndWait(AZURE.CUSTOM_DOMAIN.DOMAIN_RESOURCE_GROUP, hostname, domain, {});
    } catch (e) {
      throw new Error(e);
  }

2. Checked the domain under the resource group and found out that delegation has not been granted

Expected behavior
once domain purchased corretly, it should delegated automatically as before.
