Android:如何删除cognito中的非授权用户？

import com.amazonaws.auth.CognitoCachingCredentialsProvider;
import com.amazonaws.regions.Regions;
import com.amazonaws.services.cognitoidentityprovider.AmazonCognitoIdentityProviderClient;
import com.amazonaws.services.cognitoidentityprovider.model.AdminDeleteUserRequest;

// 创建CognitoIdentityProviderClient对象
CognitoCachingCredentialsProvider credentialsProvider = new CognitoCachingCredentialsProvider(
    getApplicationContext(),
    "YOUR_IDENTITY_POOL_ID", // 身份池ID
    Regions.YOUR_REGION // 区域
);
AmazonCognitoIdentityProviderClient cognitoClient = new AmazonCognitoIdentityProviderClient(credentialsProvider);

// 创建AdminDeleteUserRequest对象并设置要删除的用户的用户名和用户池ID
AdminDeleteUserRequest deleteUserRequest = new AdminDeleteUserRequest()
    .withUsername("USERNAME_TO_DELETE")
    .withUserPoolId("USER_POOL_ID");

// 调用adminDeleteUser方法删除非授权用户
cognitoClient.adminDeleteUser(deleteUserRequest);
