How to clear the exception to prevent being logged twice by Application Insights

I installed Application Insights into my ASP.NET Web API application. I added global exception handler to log specific exception as a custom events to App Insights:

public class AppExceptionHandler : ExceptionHandler  
{  
    private readonly IAuthEventLogger _authEventLogger;  
  
    public AppExceptionHandler()  
    {  
        _authEventLogger = DependencyResolver.Current.GetService<IAuthEventLogger>();  
    }  
  
    public override void Handle(ExceptionHandlerContext context)  
    {  
        Exception ex = context.Exception;  
        IHttpActionResult newResult = null;  
  
        while (ex != null)  
        {  
            if (ex is AppSessionException)  
            {  
                newResult = new StatusCodeResult(HttpStatusCode.Unauthorized, context.Request);  
                _authEventLogger.TrackUnauthorizedRequestEvent(context.Request.RequestUri.PathAndQuery);  
  
                break;  
            }        
        }  
  
        if (newResult != null)  
        {  
            context.Result = newResult;  
        }  
        else  
        {  
            base.Handle(context);  
        }  
    }  
}  

It works fine, But now all the exceptions are logged twice: in addition to custom events that my logger writes to, exceptions are also logged automatically in the "Failures" App Insights section.

Is there a way to not log automatically my custom exceptions as "Failures" and log all others?
