Collaboration in Dataflows?

Both I, and the individual who created this flow are priveledged users in the organization's fabric environment. The same behavior can be observed between any two individuals (working on dataflows) within the organization. That, together with the text in the message, strongly imply that this is intended behavior.

I actually can't find any official documentation on this behavior. Every search result is a microsoft community link (or similar).

The question is seeking advice on working with this limitation. Yes, I am able to take over the flow, but the workflow is highly unusual for a development team. The suggestion by Ibendlin to export the .JSON is helpful. It's workable, but the inability for team-members to view flows without wrangling a service account or manually importing the .json flows slows down development and limits knowledge transfer (both decreasing the chance that the organization will actually make the most effective use of Fabric that it could).
