尝试使用凭据管理器在我的android应用中使用Google Button登录，但登录显示Activity is cancelled by the user当从弹出窗口中选择gmail帐户时。但它显示错误为androidx.credentials.exceptions.GetCredentialCancellationException：Activity is cancelled by the user。
在这里，我在GCP中使用了web_client_id，同一个应用程序有两个Android ClientID。
所以我已经删除了AppSigningKey（SHA-1）可用的client_id，并保留了已经可用的SHA-1（即）上传密钥库（SHA-1）

val googleIdOption: GetSignInWithGoogleOption = GetSignInWithGoogleOption.Builder(WEB_CLIENT_ID).build()
val request: GetCredentialRequest = GetCredentialRequest.Builder().addCredentialOption(googleIdOption).build()

 R.id.btn_googleSignUp -> {
                val credentialManager = CredentialManager.create(this@SignUpActivity)
                coroutineScope.launch {
                    try {
                        Log.e("request.. ===", request.toString())
                        val result = credentialManager.getCredential(
