Functions

suspend fun finalizeAuthorizationResponse(preparationState: AuthorizationResponsePreparationState, credentialPresentation: CredentialPresentation? = null): KmmResult<OpenId4VpWallet.AuthenticationResult>

Calls openId4VpHolder to finalize the authentication response. In case the result shall be POSTed to the verifier, we call client to do that, and return the redirect_uri of that POST (which the Wallet may open in a browser). In case the result shall be sent as a redirect to the verifier, we return that URL. In case the result shall be returned via the Digital Credentials API, an AuthenticationForward will be returned with the result to be forwarded.
