Integrating Azure Service Bus Topic and Azure Function

Question

I created an Azure Function and selected Azure Service Bus Topic as the trigger in Visual Studio 2019. I also created a Service Bus Topic in my Azure account and have the Primary Connection String and Primary Key.

My questions are:

How can I integrate the Azure Service Bus with the Azure Function that I created? What attributes should be changed in the code generated?
How can I send a message to Azure Service Bus Topic locally on my machine? Is there any application like SQL Management Studio that can connect to my Azure Service Bus resource?

[FunctionName("Function1")]
public static void Run([ServiceBusTrigger("mytopic", "mysubscription", Connection = "ConnectionString")]string mySbMsg, ILogger log)
{
   log.LogInformation($"C# ServiceBus topic trigger function processed message: {mySbMsg}");
}

You have to change the tree attributes, and add them to the local.settings.json: You will have your Trigger like this:

[ServiceBusTrigger(
                topicName: "%MyServiceBus.Topic%",
                subscriptionName: "%MyServiceBus.Subscription%",
                Connection = "MyServiceBus.Connection")]

And your local.settings.json like this:

 {  
  "Values": {
    "FUNCTIONS_WORKER_RUNTIME": "dotnet",
    "PriorityBoardingFare.Topic": "TestEvent",
    "PriorityBoardingFare.Subscription": "Appl1cation1",
    "PriorityBoardingFare.Connection": "Endpoint=sb://xxxxxxxxx.windows.net/;SharedAccessKeyName=xxxxxxd;SharedAccessKey=adasdasdasdasdasdasd"    
  },
  "Host": {
    "LocalHttpPort": 21094
  }
}

To send or manage the service bus you have now available two options:

This is what we use at my work, its a community tool to manage the SB: https://github.com/paolosalvatori/ServiceBusExplorer
And this is the microsoft's tool: https://docs.microsoft.com/en-us/azure/service-bus-messaging/explorer.
