I'm wondering how to go about creating a block that is essentially an Ender Chest (its contents are the same regardless of which chest you check), but where any player in that world can see the contents of the Ender Chest. I was thinking of modifying the saved data for a world, but I'm struggling to understand how that even works. Are there any tutorials out there on tools I can use to work on this sort of problem? 

EDIT: I just found this post: is this about what I should be looking at for 1.16.5?

you can create a LevelCapability which stores your inventory (use Forge IItemHandler). Then create a menu which you can open for example with a custom KeyMapping. Note you need a custom Packet when you want to open the Menu from the client. Also you need to sync the Inventory to all Players which has open it (look at the ChestBlockEntity for an Example)
