At the end of onPlayerCommand function end or below the last command ending:
    SetCooldown(player, 20); // It'll set 20 seconds as default time, use this function to set cooldowns.

/*
🅴🆇🅰🅼🅿🅻🅴:

SetCooldown(player, 10); //set the instance(player)'s cooldown to 10 seconds. Remember: don't use time in milliseconds or it'll goto hours lol or you can edit it to milliseconds on your own..

SetCooldown(player, 120); //2 minute cooldown

SetCooldown(plr, 180); //3 minute cooldown for other instance plr. */
