What is the correct way to construct the request for UPlayfabMultiplayerAPI::CreateServerBackfillTicket , all server API calls use the secret key by default however this is inside of MultiplayerAPI and has an error check around the AuthenticationContext object which, since we're a server, we never login and as such never get an authentication entity token since everything normally uses the secret key.
Is this a bug with the plugin or am I missing something?
