Is there a way to anti-imput items into chests?

[Estebon5]

i've tried things than:
on inventory click:
if player's current inventory is {CHEST}:
cancel event
on swap hand items:
if player's current inventory is {CHEST}:
cancel event
on inventory click:
if player's current inventory is "CHEST":
cancel event
on swap hand items:
if player's current inventory is "CHEST":
cancel event
on inventory click:
if player's inventory is {CHEST}:
cancel event
on swap hand items:
if player's inventory is {CHEST}:
cancel event
etc...
