Humanoid Touch to Click Detector?

Hello,

After all of my desperate attempts to make this work, it hasn't been lol. I made a script for a key where if the humanoid touches the key, it is picked up. It will work better for my game if it is picked up if it is clicked. Any help? I will link the script below.

local key = script.Parent:WaitForChild('KeyUnion')
local weld = nil

key.Touched:Connect(function(hit)
    if hit.Parent:FindFirstChild('Humanoid') then
        if game.Players:GetPlayerFromCharacter(hit.Parent) then
            if game.Players:GetPlayerFromCharacter(hit.Parent).Team.Name == 'Safe' and key:IsDescendantOf(workspace) and key.Parent.Parent:FindFirstChild('Humanoid') == nil then               
                key.Parent.Parent = game.Players:GetPlayerFromCharacter(hit.Parent).Backpack
                print('hey')
            end
        end
    end
end)

script.Parent.Equipped:Connect(function()
    weld = Instance.new('Weld')
    weld.Part0 = script.Parent.Parent["Right Arm"]
    weld.Part1 = key
    weld.C0 = CFrame.new(0, -1, 0) * CFrame.Angles(-0.5 * math.pi, 0, 0)
    weld.C1 = script.Parent.Grip
    weld.Parent = script.Parent.Parent['Right Arm']
end)

script.Parent.Unequipped:Connect(function()
    if weld ~= nil then
        weld:Destroy()
        weld = nil
    end
end)

Thank you in advance.
