Parent names for CUI?

I want my UI elements only visible when playing and when in the inventory or crafting menu so not when hitting esc. The easiest way would be to make the level or exp bar the parent for instance. I have so far been unable to find more than just "Hud" and "Overlay" as parent names. Does someone no more names I could use?

 

Thanks, although it seems that Hud.Menus is actually Hud.Menu instead. It does not solve my issue of becoming invisible in the game menu and visible in the game scene and inventory screen. Therefore I will need to find another way.
