Dynamically populating "Option", "Selection" from Orders Database line items

Hi all,

At the end of my customers journey (and upon making a purchase in my store) I want to display a lightbox with a dynamic value linked to the order they have just made within a textbox, namely their selection of the option within the product.

In this case if the customer chose Friday 29th January then I’d like that date displayed in the text box within the lightbox (or whatever value was applicable for that field).

From what I have read (https://support.wix.com/en/article/velo-wix-stores-orders-collection-fields) the orders DB is read only and the line items cannot connect to data.

Is there no way of achieving this?

Many thanks in advance!
Cheers
Jonny
