How would I loop through selected objects via a plugin?

[Ethanlovir (Devz)]

I am trying to create my first plugin for Roblox Studio and I want to know how to make a table of all of the selected objects once the button is clicked.
I need to make a for i,v in ipairs(selected) do loop with the selected table containing the definitions of the selected objects in studio.

local Selection = game:GetService("Selection")

for index, value in ipairs(Selection:Get()) do
	print(value.Name)
end

local toolbar = plugin:CreateToolbar("ZFight Fixer")

local pluginButton = toolbar:CreateButton(
	"ZFight Fix",
	"Remove Z-Fighting from Selected Parts",
	"rbxassetid://12654122093"
)

pluginButton.Click:Connect(function()
	local selection = game:GetService("Selection")
	local a = 1
	for i, v in pairs(selection:Get()) do
		v.Size = Vector3(v.Size.X-(0.001*a),v.Size.Y-(0.001*a),v.Size.Z-(0.001*a)) -- line 13
		a=a+1
	end
end)

When selecting multiple parts and pressing the button, it errors on line 13, saying attempt to call a table value

@Ethanlovir

attempt to call a table value

You have Vector3( ... ) on line 13. You forgot .new

Of course it’s a brain turning off moment. Thanks!
