Is there a way to move scenes/journals from one game to another?

I wish to move some journals (Flavor text) and scenes (Just multi level maps with walls) between a Pathfinder game and a Cypher System game
No actors or items etc

I know about Shared Compendiums… however the documentation is out of date and doesn’t mention you need set an UNDERLYING SYSTEM for the compendium.

So if I create a Compendium I must select a system, if I select SF2e, I can see that compendium in the SF2e game but cannot access it in the Cypher one.
Is there another method? Exporting the JSON manually somehow, thought that was possible but no idea how
