How to retrive customer info or payment intent in succes page stripe php slim

hi i want to take amount, customer name and email on my success page but I am struggling to do.

this is my PHP server side codes which send request to stripe.

<?php
ini_set('display_errors',1);
error_reporting(E_ALL);

use SlimHttpRequest;
use SlimHttpResponse;
use StripeStripe;




require 'vendor/autoload.php';

$dotenv = DotenvDotenv::create(__DIR__);
$dotenv->load();

require './config.php';

$app = new SlimApp;

$app->add(function ($request, $response, $next) {
    Stripe::setApiKey(getenv('STRIPE_SECRET_KEY'));
    return $next($request, $response);
});

$app->get('/', function (Request $request, Response $response, array $args) {
  return $response->write(file_get_contents(getenv('STATIC_DIR') . './grid-test.html','/index-copy.html'));
});

$app->post('/checkout_sessions', function(Request $request, Response $response) use ($app)  {
  $params = json_decode($request->getBody());
  $payment_method_types = [
    'usd' => ['card'],
    'eur' => ['card'],
    'cad' => ['card']
  ];
  $products = [
    'Private' => 'prod_435646574',
  ];

  $session = StripeCheckoutSession::create([
    'success_url' => 'http://localhost:4242/success.html?session_id={CHECKOUT_SESSION_ID}',
    'cancel_url' => 'http://localhost:4242/?cancel=true',
    'mode' => 'payment',
    'payment_method_types' => ['card'],
    'payment_intent_data' => [
      'metadata' => [
        'package' => $params->package,
        'date' => $params->datepicker,
        'no of adults' => $params->adults,
        'no of children' => $params->children,
        'occupancy' => $params->occupancy,
        'tour' => $params->tour,
        'location' => $params->location,
      ]
    ],
    'metadata' => [
      'package' => $params->package,
      'date' => $params->datepicker,
      'no of adults' => $params->adults,
      'no of children' => $params->children,
      'occupancy' => $params->occupancy,
      'tour' => $params->tour,
      'location' => $params->location,
    ],
    'submit_type' => 'donate',
    'line_items' => [[
      'price_data' => [
        'currency' => 'aed',
        'product' => $products[$params->package],
        'unit_amount' => $params->amount,
      ],
      'quantity' => 1,
    ]],
    'phone_number_collection' => [
      'enabled' => true,
    ],
    
  ]);

  return $response->withJson([
    'id' => $session->id
  ]);
});




$app->run();

this is my success page which I am not able to get checkout session or payment intent details

var params = new URLSearchParams(window.location.search);
var sessionId = params.get('id');
var amount = document.getElementById('amount')

fetch('/get-session?id=' + sessionId)
.then((Response) => Response.json())
.then((session) => {
    amount.innerText = session.payment_intent.amount;
    
})
.catch((error) => {
    console.error('Error:', error);
});
