startPresentationReturningUrl
suspend fun startPresentationReturningUrl(request: RequestParametersFrom<AuthenticationRequestParameters>): KmmResult<OpenId4VpWallet.AuthenticationSuccess>(source)
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.
