Add verified domain to Azure AD

Hi! I want to add a verified domain to my Azure AD and I wonder if this is the right way to do it?

url = newUri(serviceRootURL);

varadClient =newActiveDirectoryClient(url,async() =>awaitGetAppTokenAsync());

List<ITenantDetail> tD = adClient.TenantDetails.ExecuteAsync().Result.CurrentPage.ToList();

TenantDetailtenantDetail = (TenantDetail)tD.First();

VerifiedDomainnewVerifiedDomain =newVerifiedDomain();

"newdomain.company.com";

"Email, OfficeCommunicationsOnline, OrgIdAuthentication, Intune";

"Managed";
