respondAuthRequest method

@override Future<void> respondAuthRequest({ required int id, required String iss, CacaoSignature? signature, WalletConnectError? error, })

Construct the Namespaces map for a session proposal. Uses the registered methods, events, and keys to build them. If the required namespaces is not satisfied, this function will throw a WalletConnectError. The optional namespaces are included if they exist in the registered information.
