How to report on the products that a search campaign drove

I run an E-commerce account with hundreds of brands and thousands of SKUs. I have been setting up reports for each campaign in Looker Studio: 10 PMAX and 6 Search (1XBrand, 5X Generic).

However, I cannot figure out how to show the SKUs and brands that have converted from the six search campaigns. The PMAX campaigns are straightforward, but the report breaks everywhere I turn when I try products for search campaigns. I have even tried excluding the PMAX campaign name, and that still doesn’t work.

The client wants to know what products sell through our brand campaign, but I can’t tell them.

I really appreciate any help you can provide.
