Key 'Disconnect' not found in class 'RBXScriptSignal'

[metatablesnow (snow)]

I’m currently trying to learn type annotations, and I’ve been following this tutorial by MaximumADHD.

Well trying to apply type annotations to my UI Library, I’ve ran into this issue:

Which is weird, because :Disconnect() is a “key” for RBXScriptSignals (atleast to my knowledge).

Here’s my full script:

--!strict

-- Types
type button = {
	front: Frame | CanvasGroup,
	backdrop: Frame | CanvasGroup,
	trigger: TextButton | ImageButton,
	animatingTasks: {
		[number]: RBXScriptSignal -- Idk if this is the best way to make sure it's an array
	},
	state: boolean,
}


-- Variables
local Library = {}

Library.cachedButtons = {} :: {
	[button]: button
}

--[[
	Animates the <strong>button</strong>
	<strong>button:</strong> A button class
]]
function Library.animate(button: button)
	
end

--[[
	Sets the state of all the buttons that are a descendant of <strong>object</strong>
	<strong>object:</strong> The instance to search through for nested buttons
	<strong>state:</strong> The state of which the button should be set to
]]
function Library.setStateOfButtonsNestedIn(object: Instance, state: boolean) -- I kind of need a better name for this function...
	for index, button in Library.cachedButtons do
		if button.trigger:IsDescendantOf(object) then
			if button.state == state then
			else
				if state == true then
					button.state = true
					
				else
					button.state = false
					for index, connection in button.animatingTasks do
						connection:Disconnect() -- This is whats being highlighted
					end
				end
			end
		end
	end
end

return Library

Hopefully my code isn’t too messy to read, if it is, please tell me how I can clean it up (It may be super clean and I’m just subconscious cause a year ago someone said my code sucked)

:Disconnect() is this black magic that only seems to work if you specifically do “connection = x:Connect()” in the same script beforehand

Never mind, I found my solution; I mixed up RBXScriptSignal and RBXScriptConnection. I don’t know how I didn’t catch this
