Microsoft office addin for outlook does not load on Outlook desktop app - outlook-addin

Question

I was experimenting with how to use the latest Angular-8 for Microsoft office addin.
I followed the following steps:
created a new angular project using CLI
added the manifest.xml file and updated the paths for task pane
Updated the package.json and added office-js, and other debugging liberaries.
added ssl for the localhost server.
I side loaded the addin and it works perfectly on Outlook web. I tested on many browsers and I did not find any issues.
However, When i click the addin icon in Outlook Desktop, it opens the taskpane and does not show any content.
I have not shown any configuration in the question. I will updated, Once asked by the relevant expertise.
Below are the screenshots

Outlook Desktop
Update:
Angular components are not loading in the outlook desktop add-in. I am using angular 8.
Below is the package.json.

Outlook Desktop(2013 or 2016 version) does not support es2015.
Since default behavior in angular is to compile typescript to es2015, It would not load in Outlook desktop.
I had to modify the tsconfig.app.json and add the target to es5.
