"Find my" not working with FineWoven MagSafe wallet on Iphone 13

I have a Iphone 13, iOS 17.0.2. installed. Recently purchased a new FineWoven MagSafe wallet with, according the Apple website, the "Find My" function integrated. However, when placing it the telephone does not show it in the "Find My" section, and the "+" button is not available to add it manually. I had an earlier purchase that showed me when placing it "Not your card holder" as such it was already connected to another AppleID, so I returned it to the Seller, now with the latest it didn't show it, so it is new. When placing it for the first time it showed in the display the card holder, but thereafter it stopped, when placing it now it does show me the picture anymore. Is there any solution to solve this?
