previewDigitalCredentialPresentation

Resolves an OS-mediated OpenID4VP request and returns consent metadata without releasing a credential. The caller-provided origin must already have been asserted by the platform adapter. For an unsigned request, the returned MobileWalletDigitalCredentialPreview.verifiedOrigin is the authenticated requester identity and MobileWalletDigitalCredentialRequestInfo.clientId remains null because the untrusted request-supplied client_id is ignored. For a signed request, MobileWalletDigitalCredentialRequestInfo.clientId is the authenticated Request Object client identifier after signature verification against clientIdTrustConfiguration. Unsigned (openid4vp-v1-unsigned) and signed (openid4vp-v1-signed) Digital Credentials requests are accepted. Multisigned is not.
