How a client-direct session's browser reaches the provider (ClientRealtimeSessionConfig.Transport):
'direct': the browser opens the provider's socket itself, authenticated with ClientRealtimeSessionConfig.EphemeralToken;'relay': the browser connects to MJAPI's realtime relay at ClientRealtimeSessionConfig.RelayUrl, and MJAPI holds the provider credential and opens the provider's socket.
