Configures the emulator mode behaviour: - If false, disable emulator mode always - If true, enable emulator mode always - If unset, use heuristics to decide Emulator mode notably sets insecure SSL authentication so that you can try the library out without needing a cert.
Also notably, if a TPC universeDomain is set, then this will be counted as !emulatorMode for the purposes of the heuristics. If you want emulator mode but with a TPC universe domain set, set this to true as well.
enableOpenTelemetryTracing
enableOpenTelemetryTracing?:boolean;
Enables OpenTelemetry tracing (newer, more full implementation). This defaults to false/undefined
