OPH: Cannot see master item attributes in items specification page

Hi,

    I am trying to do a POC on Oracle Product Hub, so when looking at Items detail I can only see Overview, Classification & Categories, Descriptive Attributes on the left hand side menu.

Navigation -> Desktop Manager -> Item Advanced Search --> Search.

Items Tab, Specifications Sub Tab

All the master Item attributes are not seen in the menu. I tried Attribute groups and Item pages setup for a catalog and I cannot find those attribute groups to add/show it on a page. Some of the example of master Items attribute groups are Costing, General Planning, Inventory, Manufacturing, Bills of Material etc.
