How do you make a GUI pop up from a touch event whilst having Filtering Enabled?

Title says it all,

I'm trying to make a little circle (a shop circle) and you would touch it in order to get the shop gui, but I have no idea how to do it since filtering enable makes it impossible for the script to access the localplayer. I do not wish to use remotes, but if thats the only option please tell me.

Here's my code:

local debounce = false

script.Parent.Touched:connect(function(plr)
	if game.Players:FindFirstChild(plr.Parent.Name) then
		if debounce == false then
			debounce = true
			-- how to open the shop gui? 
			
			wait(1)
			debounce = false
		end	
	end
end)
