Onesignal sdkbox.PluginOneSignal.setLogLevel not working

Hi , I integrated Onesignal through sdkbox but on Onesignal is not able to received any event. To investigate this I tried to use sdkbox.PluginOneSignal.setLogLevel() but there is no sdkbox.PluginOneSignal.LogLevel.Verbose visible as suggested in samples to pass as parameters. Am I missing something here , how to see logs on onesignal ? I did tried to pass numbers as parameters but it ends up in crash , ex sdkbox.PluginOneSignal.setLogLevel(4,4);

can you share the crash log?

and i test onesignal sample(, can’t reproduce.
