Editing ArcGis Hub Initiatives with Python: Where is the list of initiative properties?

[sccwrp]

I am working on automating hub initiative/site creation using the ArcGis API for Python. I am using the arcgis.apps.hub module. In the documentation for update() found here, it says there is a list of initiative_properties found here.

As you can see, this link is dead. Where has this documentation been moved?

Thanks

Ended up having to find the files in the github package itself and host it locally. Not a great way to distribute documentation.
