Azure Function with RabbitMQ Trigger - Queue not found in localhost

For local development I want to connect my Azure Function to a locally running RabbitMQ instance and run everything locally. But the queue is not found, even though I made sure it exists (see screenshot at the end).

The error message:

Microsoft.Azure.WebJobs.Host: Error indexing method 'Functions.ProcessEvent'. RabbitMQ.Client: The AMQP operation was interrupted: AMQP close-reason, initiated by Peer, code=404, text='NOT_FOUND - no queue 'test' in vhost '/''

Remotely using our central RabbitMQ instance I was able to receive events by using an appropriate connection string, but locally something goes wrong...

Below the program files and project files (I used VS), and the complete output.

Function.cs

using Microsoft.AspNetCore.Http;
using Microsoft.AspNetCore.Mvc;
using Microsoft.Azure.Functions.Worker;
using Microsoft.Extensions.Logging;

namespace FunctionApp1;

public class Function1
{
    private readonly ILogger<Function1> _logger;
    public Function1(ILogger<Function1> logger)
    {
        _logger = logger;
    }

    [Function("ProcessEvent")]
    public void Run(
            [RabbitMQTrigger("test", ConnectionStringSetting = "RabbitMQConnection")] string message)
    {
        _logger.LogInformation($"RabbitMQ message received: {message}");

        _logger.LogInformation("Message processing completed.");
    }
}

      "enableLiveMetricsFilters": true
    }
  }
}
 

Program.cs

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

var builder = FunctionsApplication.CreateBuilder(args);

builder.Services
    .AddApplicationInsightsTelemetryWorkerService()
    .ConfigureFunctionsApplicationInsights();
