API for cloud storage?

I'm trying to find information, e.g., how to upload and retrieve large video files to the cloud storage via an API. I found an old post:

https://community.adobe.com/t5/coding-corner-discussions/is-it-possible-to-automate-creative-cloud-file-sharing-using-apis/m-p/11625948

Which led me to this:
https://forums.creativeclouddeveloper.com/t/no-longer-accepting-new-libraries-integrations-after-march-28th/6024

Does this mean that this is not possible at the moment? I think I have a cool project in mind.
