RemoteResourceRetrieverFunction
typealias RemoteResourceRetrieverFunction = suspend (RemoteResourceRetrieverInput) -> String?(source)
Implementations need to fetch the url passed in, and return either the body, if there is one, or the HTTP header Location, i.e. if the server sends the request object as a redirect.
Wallets don't need it: at.asitplus.wallet.lib.openid.OpenId4VpProtocolClient and at.asitplus.wallet.lib.oidvci.OpenId4VciProtocolClient fetch request objects and credential offers passed by reference with HttpExchanges, which can also report status codes and headers.
