I followed the sample code shared developer.apple.com DisplayingIndoorMapsWithMapKitJS.zip
I Integrated Jwtoken correctly and there is no error in browser console however it is showing World Map.
Sample Code of index.html file.
<html>
<head>
<title>IMDF</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, user-scalable=no">
<link rel="stylesheet" type="text/css" href="/style.css">
<script type="text/javascript" src="https://cdn.apple-mapkit.com/mk/5.x.x/mapkit.js"></script>
<script type="text/javascript" src="/IMDFArchive.js"></script>

</head>
<body>
