How can I make a part only interactive with Group members?

I have successfully made a shirt that can be clicked on with a click detector and disappear(fade away).

I have been trying to make it so the click detector(disable/enable) only works when a certain ranked group member** (rank 2 and up) clicks on it.

I have failed numerous times and I am actually kinda embarrassed to put my failed script on here .-.

/ here is my little fade away script

-- Variables

local detector = script.Parent
local cooldown = false
local part = detector.Parent

-- Particles

local Glow = part.Attachment.Glow
local Sparkles = part.Sparkles

part.BrickColor = BrickColor.Random()

Glow.Color = ColorSequence.new(part.Color,part.Color)
Sparkles.Color = ColorSequence.new(part.Color,part.Color)

detector.MouseClick:Connect(function()
	if cooldown == false then
		cooldown = true
		Sparkles.Enabled = false
		Glow:Emit(1)
		Sparkles:Emit(5)
		for i = 1,20 do
			part.Transparency = part.Transparency + 0.05
			wait(0.01)
		end
		part.CanCollide = false
		detector.MaxActivationDistance = 0
		wait(math.random(30,600))
		
		part.BrickColor = BrickColor.Random()
		Glow.Color = ColorSequence.new(part.Color,part.Color)
        Sparkles.Color = ColorSequence.new(part.Color,part.Color)
		
		for i = 1,20 do
			part.Transparency = part.Transparency - 0.05
			wait(0.01)
		end
		part.CanCollide = true
		Sparkles.Enabled = true
		detector.MaxActivationDistance = 10
		cooldown = false
	end
end)
