How to import prices from csv to indesign catalog?

Hello, I have no experience to skript. However, my problem is: I have designed a catalog for a client. In the past it contained no prices, only the product descriptions, names, pictures etc.

The client used to add a separate price list (.xls) to the catalogue, so that he didn´t have to print the whole catalog new, when prices changed.

However, now he does want to reprint the catalog with the included prices (we are talking about several hundret prices, the catalog has 72 pages ... ).

Question is, whether I can somehow add fields (manually) to the existing indesign Document, that will tell InDesign to automatically grab the price for the specific product-ID I want from the CSV pricelist?

So that, when the pricelist changes next year (with prices in a different order, due to deletion of old products and newly added products), it will still find the right price via the product-ID?

Is there any easy way to do this? Neither Adobe Help nor ChatGPT give me an answer on this one ... 

Thank you so much! Holger
