Application Insights not working in locally running Azure Worker Function

Question

I am trying to get app insights to work in a local .NET 7 Worker Azure Function

public class Tools
{
    public Tools(ILoggerFactory loggerFactory)
    {
        _logger = loggerFactory.CreateLogger<Tools>();
    }
    
    [Function("test-app-insights")]
    public async Task<IActionResult> TestAppInsightsAsync([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = "tools/test-app-insights")]
            HttpRequest req)
    {
        _logger.LogInformation("HELLOFROMNEWFUNCTION");
        await Task.Yield();

        var response = 0;
        var okResponse = new OkObjectResult(response);
        return okResponse;
    }
}

I have added the code below to configure services but nothing is shown in App Insights, and there are no errors

        var appInsightsConnectionString = "MY CONNECTION STRING";

        services.AddApplicationInsightsTelemetryWorkerService((a =>
        {
            a.EnableAdaptiveSampling = false;
            a.ConnectionString = appInsightsConnectionString;
        }));

Does anyone know what I have missed?

I have this in the logging section of my host.json

"logging": {
    "logLevel": {
      "default": "Information",
      "Microsoft": "Warning",
      "System": "Warning",
      "Host": "Error",
      "Function": "Error",
      "Host.Aggregator": "Information"
    },
    "Serilog": {
      "MinimumLevel": "Information",
      "WriteTo": [
        {
          "Name": "Console",
          "Args": {
            "outputTemplate": "{Timestamp:HH:mm:ss} {Level} | {RequestId} - {Message}{NewLine}{Exception}"
          }
        }
      ]
    },
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true
      }
    }
  },

Create Application Insights Instance and copy the Instrumentation key for later use.

enter image description here

Create a Function App.
Enable Application Insights option while creating the Function App.
Select the Application Insights which we have created in the previous step.

enter image description here

Make sure that the region of Application Insights and Function App are same.
InstrumentationKey will be added in the Application Settings automatically once we enable the ApplicationInsights.

enter image description here

In Visual Studio, Create a Function App with .NET 7 Isolated.

My host.json:

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

My local.settings.json:

{

"IsEncrypted": false,
"Values": {
"AzureWebJobsStorage": "UseDevelopmentStorage=true",
"FUNCTIONS_WORKER_RUNTIME": "dotnet-isolated",
"APPINSIGHTS_INSTRUMENTATIONKEY": "Copy from Application Insights "
 }
}

My Traces in Azure Application Insights Instance:
