third party usage clarification

Hello. I understand that Adobe Stock files cannot be shared or sold to a third party, and I know that when an Adobe Stock file is used within a book as part of its design, it is permissible to sell the book itself. But what about selling the book's layout to a third party when some of that layout's design was created using RF icons from Adobe Stock? 

A book might be sold to a third party (another publisher) so that it could be sold in different countries in different languages. Is it OK to keep those design elements that use RF icons/illustrations from Adobe so long as the individual Adobe files are not shared?   In these situations the stock file is not used alone but has been incorporated into some sort of new illustration or bit of design. I've read through the information online but am seeking clarity. 

Example: Adobe stock file 321233348 was used to help create a header like the one attached. Adobe file: https://stock.adobe.com/images/set-of-magnifying-glass-icons-magnifier-or-loupe-sign-set-search-icon-concept-for-finding-people-to-work/321233348?prev_url=detail

Thank you.
