Unable to see my log messages below than Warning on Azure Monitor

I created an Azure Static Web App. I can see the requests of my API functions being executed in application insights (Monitor). But I can't see the log messages below than Warning. In the Azure Function, I'm logging messages as shown below:

        _logger.LogTrace($">>> Log Trace");
        _logger.LogDebug($">>> Log Debug");
        _logger.LogInformation($">>> Log Information");
        _logger.LogWarning($">>> Log Warning");
        _logger.LogError($">>> Log Error");
        _logger.LogCritical($">>> Log Critical");

        Console.WriteLine($">>> Console WriteLine");

As you can see below it is missing Trace Debug Information logging messages.

Below is my .csproj file.

Below is my host.json file.

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "logLevel": {
        "default": "Information",
        "Function": "Information"
      },
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request",
        "logLevel": {
          "default": "Trace"
        }
      },
      "enableLiveMetricsFilters": true
    },
    "logLevel": {
      "default": "Information",
      "Function": "Information"
    }
  }
}

What is missing in order to see all of my logging messages ?

I have tried with your code and done changes in Program.cs file.

 services.Configure<LoggerFilterOptions>(options =>
 {
     LoggerFilterRule logfilter = options.Rules.FirstOrDefault(rule => rule.ProviderName
         == "Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider");

     if (logfilter is not null)
     {
         options.Rules.Remove(logfilter);
     }
 });

• Now I am able to see the Log Information traces along with other severity levels.

My Program.cs file:

using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
    .ConfigureServices(services =>
    {
        services.AddApplicationInsightsTelemetryWorkerService();
        services.ConfigureFunctionsApplicationInsights();
        services.Configure<LoggerFilterOptions>(options =>
        {
            LoggerFilterRule logfilter = options.Rules.FirstOrDefault(rule => rule.ProviderName
                == "Microsoft.Extensions.Logging.ApplicationInsights.ApplicationInsightsLoggerProvider");

            if (logfilter is not null)
            {
                options.Rules.Remove(logfilter);
            }
        });
    })    
    .Build();
host.Run();

• And I am able to log all the traces with my default code with the below configuration as well.

My host.json file:

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    },
    "logLevel": {
      "default": "Information"
    }
  }
}

• When we create Function App,Initially Application Insights is configured for local.
• Disconnect it and change it to Azure Application Insights.

Refer this SOthread to configure it.
