dimension:
whenever an entity has a item with thedimensiondata component, no matter if the dimension is trying to enter is locked, it will enter as long as the component's dimension matches the one trying to enter.Example:
/give @s minecraft:ender_eye[dimension_locker:dimension="minecraft:the_end"]cant_enter_ender_chest:Doesn't let the item inside the ender chest, nor any item containing it (shulker boxes, bundles, etc).

Example:
/give @s minecraft:ender_eye[dimension_locker:cant_enter_ender_chest={}]un_despawnable:Quite simple, prevents the item from despawning after the standard 5 minutes, can be paired with the
damage_resistantdata component to make undestructible items.Example:
/give @s minecraft:ender_eye[dimension_locker:un_despawnable={}]
