Laravel：从ChargeBee接收数据

我设法在ChargeBee中创建了一个客户，但我不知道如何访问它的每个值

为了接收信息，我使用以下代码，它非常适合我

ChargeBee_Environment::configure("mysite-test","test_afhjsfslfsfslk438493sshgeh");
        $result = ChargeBee_Customer::retrieve("16HHGDGJslfksds");
        $customer = $result->customer();
        $card = $result->card();

通过执行dd（$result），我得到以下结果：

ChargeBee_Result {#356 ▼
  -_response: array:1 [▼
    "customer" => array:22 [▼
      "id" => "16HHGDGJslfksds"
      "first_name" => "User"
      "last_name" => "Test"
      "email" => "user@mail.com"
      "phone" => "555667788"
      "auto_collection" => "on"
      "net_term_days" => 0
      "allow_direct_debit" => false
      "created_at" => 1603420880
      "taxability" => "taxable"
      "updated_at" => 1603420880
      "pii_cleared" => "active"
      "resource_version" => 1603420880216
      "deleted" => false
      "object" => "customer"
      "billing_address" => array:6 [▶]
      "card_status" => "no_card"
      "promotional_credits" => 0
      "refundable_credits" => 0
      "excess_payments" => 0
      "unbilled_charges" => 0
      "preferred_currency_code" => "USD"
    ]
  ]
  -_responseObj: array:1 [▼
    "customer" => ChargeBee_Customer {#358 ▶}
  ]
}

例如，如何获取该客户的id？？？在这种情况下，它是16HHGDGJSLFKSD
