passing injected parameter

How can I inject instances in the method similar to CancellationToken ??

```
public class CustomService : ICustomService
{
public static ICustomService Null => null;
}
public interface ICustomService
{

}
public interface ICustomJob
{
void Execute(ICustomJob customToken);
}
public class CustomJob: ICustomJob
{
public void Execute(ICustomService customService)
{
Thread.Sleep(30000);
}
}

RecurringJob.AddOrUpdate(a => a.Execute(CustomService.Null), Cron.Minutely());

```
