How do I make my script repeat itself when you call the same function?

So, I am currently working on a game, and I made a LocalScript in the StarterGui that controls a ProximityPrompt in the Workspace. Basically, what the script does is it makes the player sit down after the ProximityPrompt is triggered.

This is the LocalScript in the StarterGui:

local prox = game.Workspace:WaitForChild("Setup").Chair1.Chair1.ProximityPart.ProximityPrompt
local humanoidRPart = game.Players.LocalPlayer.Character:WaitForChild("HumanoidRootPart")
local humanoid = game.Players.LocalPlayer.Character:WaitForChild("Humanoid")
local chair = game.Workspace:WaitForChild("Setup").Chair1.Chair1.Seat

local cam = game.Workspace.CurrentCamera

local camPart = game.Workspace:WaitForChild("Setup").ComputerCamPart

local function camSnap()
    repeat
        cam.CameraType = Enum.CameraType.Scriptable
        wait(0.1)
    until cam.CameraType == Enum.CameraType.Scriptable

    cam.CFrame = camPart.CFrame
end

local UIS = game:GetService("UserInputService")

local cooldown = 1
local debounce = false
local sitting = false

local function onSit()
    if debounce == false then
        camSnap()
        debounce = true
        chair.Disabled = false
        humanoidRPart.CFrame = CFrame.new(36.2, 3.46, -174.2)
        humanoid.Sit = true
        prox.Enabled = false
        humanoid.JumpPower = 0
        wait(cooldown)
        debounce = true
        script.Parent.MainPcBackground.Enabled = true
        script.Enabled = false
    end
end

prox.Triggered:Connect(onSit)

After the player sits down, a Gui Pops-Up, where there is an Exit Button that the players can click to make the Gui disappear and re-enable the ProximityPrompt.

local cam = game.Workspace.CurrentCamera
local player = game.Players.LocalPlayer
local character = player.Character
local humanoid = character:WaitForChild("Humanoid")

local seat = game.Workspace:WaitForChild("Setup"):WaitForChild("Chair1"):WaitForChild("Chair1"):WaitForChild("Seat")
local prox = seat.Parent:WaitForChild("ProximityPart"):WaitForChild("ProximityPrompt")

local ExitButton = script.Parent

ExitButton.MouseButton1Click:Connect(function()
    ExitButton.Visible = false
    script.Parent.Parent.Parent.Enabled = false
    wait(1)
    cam.CameraType = Enum.CameraType.Custom
    cam.CFrame = character:WaitForChild("Head").CFrame
    humanoid.JumpPower = 50
    humanoid.Jump = true
    seat.Disabled = true
    prox.Enabled = true
    wait(1)
    script.Parent.Visible = true
end)

These two scripts work just fine, and there are No Errors. However, my problem is that it doesn't do anything when the ProximityPrompt Re-Enables, after the player Triggers it a second time. Is there a way to make it so that when you Exit the GUI, the ProximityPrompt will work again?
