conditoinally show a scene fragment

[Kismalyn]

hi hive-dev-mind.

I have an addon that I need to show, via an on/off toggle conditionally. I can't get the fragment to stay hidden, after first enabling it, and then disabling it.

I saw this post and tried the following:

        fragment:SetConditional(function() 
		return settings.activeWindow
	end)

but it doesn't work, I still get the fragment showing even with the activeWindow var is false.

Ive also tried conditional code in a conventional callback, like this:

function Ui:ShowHideTLC(makeVis)
	local sceneHUD = SCENE_MANAGER:GetScene("hud")
	local sceneUI = SCENE_MANAGER:GetScene("hudui")
	local TLC = AddOnWindow
	local tlcFragment = ZO_SimpleSceneFragment:New(TLC)
	
        TLC:SetHidden(not makeVis)

	if (makeVis == true and settings.activeWindow == true) then
		sceneHUD:AddFragment(tlcFragment)
		sceneUI:AddFragment(tlcFragment)
	else
		sceneHUD:RemoveFragment(tlcFragment)
		sceneUI:RemoveFragment(tlcFragment)
	end
end

local function tlcFragmentChange(oldState, newState)
	if (newState == SCENE_FRAGMENT_SHOWN) then
		self:ShowHideTLC(true)
	elseif (newState == SCENE_FRAGMENT_HIDDEN) then
		self:ShowHideTLC(false)
	end
end

-- this is bound to a key
function Ui:ToggleShow()
	settings.activeWindow = not settings.activeWindow
	self:ShowHideTLC(settings.activeWindow)
end

-- this is in the init function
local tlcFragment = ZO_SimpleSceneFragment:New(AddOnWindow)
tlcFragment:RegisterCallback("StateChange", tlcFragmentChange)

I almost get the behaviour I want with this, except that once Ive toggled the addon visible, it will always appear on the HUD, even if I retoggle it off again (if that makes sense)

I have a feeling Im overcomplicating it, as I tend to do, but I cant figure it out. I'm new to Lua, let alone ESOUI.

Thanks!
