1. A concise explanation of the problem you're experiencing.
I copied the codes of the first app which is at the link below but it gives me a blank white page; nothing in it. I have run it on multiple computers and with multiple browsers but the results are the same. My access token is already there in the template, so I have nothing to do but just copying and pasting it to glitch. But it won't let me get it.
2. A minimal code example. If you've found a bug, this helps us reproduce and repair it.

<div id="cesiumContainer" style="width: 700px; height:400px"></div>
<script>
Cesium.Ion.defaultAccessToken = 'MY ACCESS TOKEN';
var viewer = new Cesium.Viewer('cesiumContainer');

3. Context. Why do you need to do this? We might know a better way to accomplish your goal.
Just want to build my first app by following the tutorial.
4. The Cesium version you're using, your operating system and browser.
I didn't think I need to install Cesium because the codes above do not refer to my own Cesium.
