Is there any way to give to on rightclick event on a off hand item?

Is there any way to give to on rightclick event on a off hand item? The code I made only works when the shield is in the main hand but I want it to work in both hands. Here is my code:

command /shield:
    trigger:
        give player 1 netherite sword named "&b&lSpecial Shield" 

on damage:
    if name of attacker's held item is "&b&lSpecial Shield":
        add 200 to the damage

on rightclick holding netherite sword:
    if name of player's held item is "&b&lSpecial Shield":
        make player execute command "/effect give @p minecraft:fire_resistance 999999 255"
        make player execute command "/effect give @p minecraft:slow_falling 999999 255"
        make player execute command "/effect give @p minecraft:night_vision 999999"
        make player execute command "/effect give @p minecraft:conduit_power 999999"
        make player execute command "/effect give @p minecraft:haste 999999 255"
        make player execute command "/effect give @p minecraft:strength 999999 255"
        make player execute command "/effect give @p minecraft:instant_health 999999"
        make player execute command "/effect give @p minecraft:invisibility 999999"
        make player execute command "/effect give @p minecraft:resistance 999999 255"
        make player execute command "/summon minecraft:lightning_bolt"
        make player execute command "/weather storm"
        make player execute command "/give @p milk_bucket 1"

You can check for a player's off hand too. if player's offhand tool is a stick. Also why are you using console commands? All those can be done with just basic skript effects. And @p doesn't exist in skript so it wouldn't work anyways.
