Making a cooldown that shows on an action bar

[HollowwwMC]

I'm confused on how to make a cooldown and how to make it show up on the action bar. For example:

on right click:
    if player's tool is {customitem:coolsword}:
        apply strength 2 to player for 20 seconds
        apply speed 2 to player for 20 seconds

How would I make this have a cooldown and have it show on the action bar?

Hey,

Action Bar (Effect) - Skript

Sends an action bar message to the given player(s).

Here:

on right click:
    if player's tool is {customitem:coolsword}:
          set {coolswordcooldown::%player's uuid%} to 20
          apply strength 2 to player for 20 seconds
          apply speed 2 to player for 20 seconds

every second:
    if {coolswordcooldown::%player's uuid%} is more than 0:
        subtract 1 from {coolswordcooldown::%player's uuid%}
        send action bar "&cCooldown: %{coolswordcooldown::%player's uuid%}%" for 1 second

I would actually recommend like

on right click:
    if player's tool is {customitem:coolsword}:
        if {Cooldown::%player's uuid%} is set:
            stop
        else:
            set {Cooldown::%player's uuid%} to 30 #In seconds
            apply strength 2 to player for 20 seconds
            apply speed 2 to player for 20 seconds
            send action bar "&7Cooldown: %{Cooldown::%player's uuid%}%" to player
            while {Cooldown::%player's uuid%} is more than 0:
                wait 1 second
                remove 1 from {Cooldown::%player's uuid%}
                send action bar "&7Cooldown: %{Cooldown::%player's uuid%}%" to player
            delete {Cooldown::%player's uuid%}
