Personal toolbar button in Forge Viewer not appearing

Question

I followed the tutorial to learn Autodesk Forge. I linked my BIM 360 account to the Forge Viewer. I would now like to add extensions to it and have a button on the toolbar that links to my extensions.

However when I follow the extension tutorial, nothing shows up. I also tried this one https://forge.autodesk.com/en/docs/viewer/v5/tutorials/toolbar-button/#before-you-begin and nothing appear.

I do not know what I am doing wrong since it seems to work if we follow the tutorial...

I am working on VS code

Right now, my code looks like this in the index.html file : enter image description here

The rest is exactly like the tutorial except that I replaced "MyAwesomeExtension" with "PieChartExtension"

Answer 1

One thing to try will be to switch your var config3d to the following:

var config3d = {extensions: ['PieChartExtension']}

The reason might be, your syntax might be affecting and that is why the Viewer does not understand what to load. Did you check the console for any messaging?
