I need to display a custom field in Admin Order Product Details section

[Luminence]

I am developing a module for Prestashop. The module is for TShirt customization and have integrated the third party app for design.

 

I have taken the designID and attached it to a new field I added to the table "cart_product".

 

Now I need to get that designID to the Admin Order Details page, please what hook do I use?

 

Remember, first I need to get each designID pertaining to each product in the order (cart_product), then display it in the Products section when you go to Admin -> Orders -> View an Order -> Products section down where Customization is normally listed.

 

Thanks.
