How to make hub using worlds and not bungee?

I am using 1.12.2 spigot
with multiverse.
I have a hub-like server but with worlds instead of linked servers.
My question is: How can I make a static inventory in one specific world that players cannot edit and this inventory will be separate from all the other worlds, including the items and lores/names of my choosing in the slots i want?
All other worlds will have a shared inventory.

Any help will be greatly appreciated. I have looked into MultiInv but it is outdated and I don't think it has a static inventory feature.

any ideas will help!

You can use my plugin, LobbyAPI. With this, you can have separate inventories for different worlds. It also handles registering custom worlds and has a GUI system if you need a hub menu.

 

It looks like a very nice plugin, however, it doesn't fit my needs. I am trying to get a hub-like feel more or less. I have already made the gui, now I need to figure out how to make it so that in world Hub all player inventories are oriented with the compass and cannot be edited, but only in that world. Thank you for the suggestion.
