--create scene which I can add to the main menu:
local tlw, texture

tlw:SetAnchor(CENTER, GuiRoot, CENTER, 0, 0)
tlw:SetHidden(true)
texture = WINDOW_MANAGER:CreateControl(nil, tlw, CT_TEXTURE)
texture:SetTexture("/esoui/art/icons/poi/poi_groupboss_complete.dds")
texture:SetAnchorFill(tlw)
 
local fragment = ZO_FadeSceneFragment:New(tlw)
 
local myAddonScene = ZO_Scene:New("myAddonScene", SCENE_MANAGER)
myAddonScene:AddFragmentGroup(FRAGMENT_GROUP.UI_WINDOW) --standard UI elements such as mouse or keybind strap
myAddonScene:AddFragment(fragment)
