Cannot find PCG Demo graphs

Hello,

I've been trying to look into the PCG feature on unreal 5.2 following online tutorials which tell me to load up a demo PCG graph (simple forest in that case). My problem is that when I go to look at the instance graph list, it is [completely empty](https://i.imgur.com/ccfQMUN.png). What do I need to do to get those example graphs so I can try to understand how they work? I could start building my own but it's not exactly the best for me to learn PCG.

Thanks.
