I'm looking for the location of Contacts images Suggestions folder

I've lost the location of a folder I'm looking for. I'm on Mac Sequoia 15.5 and using the Contacts app. When editing a contact photo, this window opens: I added the Indian picture to /Library/User Pictures and still do not see it in Suggestions - which im guessing I wouldn't have. But, it's not in any of the available selections when editing the Contact Acme Lock. New image location: I'd like to know the location of this Suggestions folder so that I can add another image and remove an earlier one. Where on the filesystem should I be looking?
