amazon-cloudformation - 注册时唯一的用户名和唯一的电子邮件放大 Cognito React

Question

我正在研究反应项目。我遇到的问题是，我可以创建唯一的用户名或唯一的电子邮件。如果我选择用户名是唯一的，我可以使用相同的电子邮件注册多个帐户，但我不会那样，如果我选择电子邮件作为唯一的用户名是由 aws 自动生成的，这也不是我想要的。有没有可能让我拥有唯一用户选择的用户名和唯一电子邮件的方法。如果可能的话，我希望在 CloudFormation文件 amplify/backend/auth/{projectname}/template.yaml期间以编程方式发生这种情况
