im trying to make it so when button clicked it heals but i need to fix my code any one help?

script.Parent.Fire.OnServerEvent:Connect(function(player)
	local Figure = script.Parent
	local Head = Figure:WaitForChild("Head")
	local Humanoid = Figure:WaitForChild("Humanoid")
	-- regeneration
	while true do
		wait(0.5)
		while Humanoid.Health < Humanoid.MaxHealth do
			wait(0.125)
			Humanoid.Health = Humanoid.Health + 1
		end

		wait(20)
		end
		wait(35)
end)

this works on its own but I want it to be on button click not automatic

	local Figure = script.Parent
	local Head = Figure:WaitForChild("Head")
	local Humanoid = Figure:WaitForChild("Humanoid")
	-- regeneration
	while true do
		wait(0.5)
		while Humanoid.Health < Humanoid.MaxHealth do
			wait(0.125)
			Humanoid.Health = Humanoid.Health + 1
		end
