How do I identify passkeys in my Keychain Access and determine which site they are for?


I have a number of edge case questions about Passkeys but I'll start simple. I am developing the ability to use Passkeys for my web application. In the process, I've already created one or two passkeys that I would like to delete eventually. But I suspect I will need to create several more during testing that I'd like to delete as well. Plus, just in general, I'd like to be able to see the passkeys I have in my Keychain... not sure why --- curiosity I suppose.

Can someone tell me how to identify them and tie them to specific web sites / web services?
