How do I use Click Detector with filtering enabled?

I'm working on a store script where a player could click on a mannequin to be able to buy it. How do I make it so that this works with filtering enabled on?

script.Parent.MouseClick:connect(function()
	print("Click Detected")
	-- other stuff
end)

I have a system, where I make a click detector, and the click detector has a remote event inside of it. In a local script in the client when you click part it checks if the part has a click detector and the remote event in it. Then it just fires the remote event. For a server script insteadde of connecting a function to the click detector, I connect it to the remote event.
