How can I configure Mass Transit Courier using Bus.Factory.CreateUsingRabbitMq?

I am using Mass Transit Version 7 and I am facing a problem and I should note that I am a beginner in Mass Transit, so excuse me for my simple question.

My Question is How to Configure Mass Transit Courier using Bus.Factory.CreateUsingRabbitMq.

To configure activities without using a container, use the specific methods for compensate and execute activity hosts. There are different overloads if you need to specify an activity factory method or other configure the endpoint.

Bus.Factory.CreateUsingRabbitMq(cfg =>
{
    cfg.Host(...);

    Uri compensateAddress = default;

    cfg.ReceiveEndpoint("activity-compensate", x =>
    {
        x.CompensateActivityHost<TActivity, TLog>();

        compensateAddress = x.InputAddress;
    });

    cfg.ReceiveEndpoint("activity-execute", x =>
    {
        x.ExecuteActivityHost<TActivity, TArguments>(compensateAddress);
    });
});
