Yep, to be clear, this is utilizing webauthn under the hood, saving the seed phrase as a largeBlob. LargeBlob support requires an enclave that issues two keys: one for the webauthn credential (which is unused because most providers don't support secp256k1), and a corresponding largeBlob key to enc/decrypt the blob.
