How to make a gui not appear while you're in a dialog?

Hello. I'm trying to make a dialog system with an NPC where I use magnitude to detect if the player is close to the NPC. If he is, then he has to press e and a gui will show up showing "press e to interact". Everything works fine, but while the npc is chatting, the interact gui keeps appearing.

-- Script inside the model
local UIS = game:GetService("UserInputService")
local debounce = false
local modelName = "Dave"
local model = script.Parent
local interact = game.ReplicatedStorage.Interact
local dialog = game.ReplicatedStorage.Dialog

local dist = 5

while true do
	for _, v in pairs(game.Players:GetChildren()) do
		local char = v.Character or v.CharacterAdded:Wait()
		local playerGui = v:WaitForChild("PlayerGui")
		
		if (char:WaitForChild("HumanoidRootPart").CFrame.p - model.HumanoidRootPart.CFrame.p).magnitude <= dist then
			game.ReplicatedStorage.Remotes.TalkDave:FireClient(v, dist)
		else
			interact.Parent = game.ReplicatedStorage
		end
		
		wait()
	end
	wait()
end

-- Local script in startergui
local UIS = game:GetService("UserInputService")
local debounce = false
local modelName = "Dave"
local model = game.Workspace.Dave
local interact = game.ReplicatedStorage.Interact
local dialog = game.ReplicatedStorage.Dialog

local player = game.Players.LocalPlayer

game.ReplicatedStorage.Remotes.TalkDave.OnClientEvent:Connect(function(dist)
	local char = player.Character or player.CharacterAdded:Wait()
	local playerGui = player:WaitForChild("PlayerGui")
	local humanoid = char:WaitForChild("Humanoid")
	
	if dialog.Parent == playerGui then
		interact.Parent = nil
	end
	
	if (char:WaitForChild("HumanoidRootPart").CFrame.p - model.HumanoidRootPart.CFrame.p).magnitude <= dist then
		interact.Parent = playerGui
		
		UIS.InputBegan:Connect(function(input)
			if input.KeyCode == Enum.KeyCode.E and not debounce and interact.Parent == playerGui then				
				debounce = true
				
				humanoid.WalkSpeed = 0
				interact.Parent = nil
				dialog.Parent = playerGui
					
				local message = "Life in Saffron Village is so cool! We have a forest where we get our food from, and beyond the forest is Port Savaria, where we can go to other towns and cities."
				
				dialog.NameBox.TextLabel.Text = modelName
				
				for i = 1, #message do
					dialog.Text.TextLabel.Text = string.sub(message, 1, i)
					wait()
				end
				
				dialog.Continue.Visible = true
				dialog.Cancel.Visible = true
				
				dialog.Continue.MouseButton1Down:Connect(function()
					dialog.Continue.Visible = false
					dialog.Cancel.Visible = false
					dialog.NameBox.TextLabel.Text = ""
					dialog.Text.TextLabel.Text = ""
					dialog.Parent = game.ReplicatedStorage
					interact.Parent = game.ReplicatedStorage
					
					humanoid.WalkSpeed = 30
				end)
				
				dialog.Cancel.MouseButton1Down:Connect(function()
					dialog.Continue.Visible = false
					dialog.Cancel.Visible = false
					dialog.NameBox.TextLabel.Text = ""
					dialog.Text.TextLabel.Text = ""
					dialog.Parent = game.ReplicatedStorage
					interact.Parent = game.ReplicatedStorage
					
					humanoid.WalkSpeed = 30			
				end)
			end
			
			wait(1)
			debounce = false
		end)
	else
		interact.Parent = game.ReplicatedStorage
	end
end)

I am aware of the while loop from the server script that causes it, but I can't find a way to make the interact gui stop appearing while in dialog.

Nevermind, found a solution to make the textlabel inside the interact gui invisible and when the dialog gui wasn't on screen anymore it would be visible again.
