How to get Catalog Item Category Details

Hi Developers,

As we all know one Catalog Item can be part of multiple Categories (we can add multiple categories in the 'Category' related list of the catalog item). How do we get the Category name from which the catalog item got submitted?

Example:

Catalog Item: Apple iPhone 13 pro

Category: Mobile, Iphones  (on the catalog form Category was given as Mobile, and in the related list, added on more category as 'iPhone'

User submitted the request from the category 'iPhone', where is this information stored on the request/ITEM that it has been presented with the category called 'iPhone'?

Thanks in advance
