HMI Tab (Deprecated)
An HMI tab is a user interface overlay that includes multiple elements. We recommend that you start your own tabs based on the existing Tabs within the HMI Demoscene
Activation of the tabs can be done either through a button a dropdown menu or a PLC-signal.

HMI Tab structure
Do not rename the GameObjects within the HMI-prefab. The tab’s content consists of two areas: OverlayContent for HMI-elements displayed as a screen overlay, and WorldspaceContent without a Canvas where elements automatically receive a canvas in “WorldSpace” render mode. These elements will be placed in the 3D scene.”
If you use HMI-messages in one of the areas the HMI-tab will detect this and manage them.
