So you were actually doing it correctly but instead, you need to select "insert all items" and you can also ask it to search for that specific field called "persona" and it should do a better job. I made the change for you so you can check it out if it helps! Let me know if you run into any issues!
There we go, I missed that "persona" had a subfield called "value" so it was not detecting it properly so I just added that word to the prompt and now working. if any "value" from "persona" from this list /recordsFound contains "VP" then true, otherwise false
