Unable to see Datadog logs with Serilog.Sinks.Datadog.Logs Version 0.5.4 on Azure Function App

Create .NET 9.0 Isolated Azure function to use Serilog.Sinks.Datadog.Logs version 0.5.4 and Serilog version 4.2.0.

I have tested the same with .NET 9.0 isolated Azure function and it worked as expected.

public static class Function1
{
    [Function("MyFunction")]
    public static void Run(
        [TimerTrigger("0 */2 * * * *")] FunctionContext context)
    {
        // Serilog logs
        Log.Information("C# Timer trigger function executed at: {time}", DateTime.Now);
        Log.Information("Time in UTC: {time}", DateTime.UtcNow);
        Log.Information("This is Datadog LOG");

        // ILogger logs
        var logger = context.GetLogger("Function1");
        logger.LogInformation("This is an Azure Functions log message.");
        logger.LogWarning("This is a Warning message");
        logger.LogError("this is a error message");

    }
}

program.cs:

var host = new HostBuilder()
    .ConfigureFunctionsWebApplication()
    .ConfigureServices(services =>
    {
        Log.Logger = new LoggerConfiguration()
            .WriteTo.DatadogLogs(apiKey: "<DataDog_APIKey>")
            .CreateLogger();
    })
    .Build();

host.Run();

host.json:

{
    "version": "2.0",
    "logging": {
        "applicationInsights": {
            "samplingSettings": {
                "isEnabled": true,
                "excludedTypes": "Request"
            },
            "enableLiveMetricsFilters": true
        }
    }
}

Console Output:

        MyFunction: timerTrigger
