App Connect Flow documentation

Is there any documentation on app connect flow other than the introduction?

The intro mentions the following use cases which I’m interested in but I can’t find anything other than a few folk asking the same thing…

• Query for fresh data from server and then insert in data store only when needed.
• Query different API sources for data - filter and transform data, then use it on your page.
• Query remote data, process it first in a flow, filter and transform - and then use it when done.
• Query regularly remote service for new data and act when available
• Fetch remote data from multiple data sources, transform, filter and use as new data

If it’s a case of playing around and working it out I guess that’s fine, but some documentation would be great to save some time.

Thanks.
