How to Send Notifications Using sendMulticast with Token Chunking in kreait/laravel-firebase?

I’m using the kreait/laravel-firebase package to send push notifications to a large number of users. Since I need to send notifications to a large number of device tokens, I’m trying to use the sendMulticast method and chunk the tokens to respect the Firebase limit of 500 tokens per request.

$all_data = array_chunk($recipients, 500); // Split tokens into chunks of 500

foreach ($all_data as $deviceTokens) {
    $message = CloudMessage::new()
        ->withNotification($notification)
        ->withData([
            'extra_data' => 'some_data',
        ]);

    // Send the message to the chunk of tokens
    $result = $messaging->sendMulticast($message, $deviceTokens);
    dd($result); // Check the result for each batch
}

Showing Bellow Errors :

#message: "Operation is not implemented, or supported, or enabled."
    #code: 501
    #file: "C:\xampp\htdocs\sajida-fieldforce\vendor\kreait\firebase-php\src\Firebase\Exception\Messaging\MessagingError.php"
    #line: 22
    #errors: array:1 [▼
      "error" => array:3 [▼
        "code" => 501
        "message" => "Operation is not implemented, or supported, or enabled."
        "status" => "UNIMPLEMENTED"
      ]
    ]
