How to Prevent Remote event firing multiple times?

Hello,i am making a game where the player has abilities and can use then when hitting a button on the keyboard and has a 'regen' time which takes 11 to 12 seconds and what can i do to prevent the player from firing the remote event again.

--Server script
function debounce(func)
    local isRunning = false   
    return function(...)       
        if not isRunning then
            isRunning = true
 
            func(...)          
 
            isRunning = false
        end
    end
end
local ReplicatedStorage = game:GetService("ReplicatedStorage")
local shoot = ReplicatedStorage.ShootGaunletA
shoot.OnServerEvent:Connect(debounce(function(player, ability, cursor)
	if cursor ~= true then
		--kick player 
	end
	if ability ~= "PowerPunch" then
		--kick player 
	end
 	print(ability)
	

wait(11) --around somewhere here to prevent hackers 

	
end))

--local script
local ReplicatedStorage = game:GetService("ReplicatedStorage") 
function run()
 script.Parent.PowerPunch.Bar:TweenSize(UDim2.new(0,200, 0, 30), "Out", "Linear", 10,true, function()
	local UIS = game:GetService("UserInputService")

UIS.InputBegan:connect(function(Input,Processed)
  if not Processed then 
	if script.Parent.PowerPunch.Bar.Size == UDim2.new(0,200,0,30) then
    local MouseInput = Input.UserInputType 
    local KeyCode = Input.KeyCode 
     if KeyCode == Enum.KeyCode.V then
	    script.Parent.PowerPunch.Bar:TweenSize(UDim2.new(0,0, 0, 30), "Out", "Linear", 0.5,true)
		 wait(0.5)
           local ReplicatedStorage = game:GetService("ReplicatedStorage")
           ReplicatedStorage:WaitForChild("ShootGaunletA"):FireServer("PowerPunch",true)
		  run() -- any better way then doing this?
     end
    end
 end
end)
	
end)

end

run() -- any better way then doing this?

Thank you!
