In addition to the inventory post that already exist, I want to be able to give players items to consume/spawn only usable in my world.

For example, if I make a Minecraft-esque world every player would find a starter kit in their inventory with a shovel, axe, torch and pickaxe. When leaving the world the items would disappear. Or a flare gun players can use to find each other on super large worlds.

Assuming persistence exists, a tick box would exist on the imaginary item component to either make it disappear on switching world or you keep it forever (Or until consumed?)
