How to make a player hold on this E Circle?

Hey everyone,

I just watched a YouTube video on E Circles. Everything works, but I want the player to hold on the E Circle, and then it does action.

Here is my script:

local inputservice = game:GetService("UserInputService")
local teleportservice = game:GetService("TeleportService")

inputservice.InputBegan:Connect(function(i,g)
	if i.UserInputType == Enum.UserInputType.Keyboard then
		if i.KeyCode == Enum.KeyCode.E then
				local Mag = (workspace.Map.MainTeleport.Doorknob.Position-game.Players.LocalPlayer.Character.HumanoidRootPart.Position).magnitude
			if Mag <= 22 then
				workspace.Map.MainTeleport.Doorknob.Gui.EnterButton.BackgroundColor3 = Color3.fromRGB(145,145,145)
				wait(.1)
				workspace.Map.MainTeleport.Doorknob.Gui.EnterButton.BackgroundColor3 = Color3.fromRGB(255,255,255)
				teleportservice:Teleport(5190764174, game.Players.LocalPlayer.Character)
			end
		end
	end
end)
