Content Delivery - Entities

Hello,
I am trying to build a POC for Content Delivery - Entity component System [ECS].

I went through this doc:
https://docs.unity3d.com/Packages/com.unity.entities@1.0/manual/content-management.html
and this git hub repo:

There is no example of how I can load the content archive.

Can someone give me a lead on this.
