App Service Logging of System.Diagnostics.Trace.TraceError calls

I have an appservice(windows) .net core 3.1 using System.Diagnostics.Trace.TraceError statements. I am able to see the output in the visual studio debugger but can not see it in the streaming logs output of the app service. I have tried two documentation (doc 1 , doc 2) whose steps do not look coherent . I found_logger.LogInformation statements are working and output can be seen in console during local debugging and streaming logs of the app service. I can not see any logs from the System.Diagnostics.Trace.TraceError statements that I have written. I feel there is some gap in the documentation as I have tried this on a simple hello world application.
