Can't figure out how to share colors, styles, and components

I have a project with colors, styles. components and artboards.  Want to re-use the document assets these in multiple projects - and be able to edit them in one place too!  Seems to be exactly what the cloud is for, right?

But...

From document assets, I click share, and create a library.  About 10 minutes later it shows up in my creative cloud library browser but it is empty, there is nothing in it.

However, in my library browser when I look at the my work with original project I see all the document assets.

I'm sure this is really easy...
