Account Abstraction getWebAuthnCredential

const credential = await createWebAuthnCredential({ name: 'Wallet' })

When a user clicks a "Log in" button it'd be nice to have a getWebAuthnCredential function to request a WebAuthnCredential from a user and return a credential that can be used to create a Coinbase smart account wallet.

If this were to be the case would the same credential deterministically create the same Coinbase Wallet?

So instead we're storing the user's ID in a contract upon creation and looking up their smart wallet from that (after making a UserOp to create the wallet ofc... 😅 AA is fun
