Lumen schedule:work and integration of schedule jobs and queue

Hey everybody!

I'm using the lastest version of Lumen for an API project, that needs a recurring task operation. Lumen itself has no documentation on that. For the laravel documentation, the command schedule:work is proposed for local testing. But Lumen seems to lack this command. Is there no other way for testing this besides running schedule:run (which seems to only fire the scheduled job once) or implementing a "real" cron job on my local machine?

The other question: I don't yet fully understand how scheduled queueable jobs work. Are they anyhow connected to queues? Do they need the queue db table? It seems to be not the case, when I use a Job, however I'm not sure. Could someone give me a brief explanation about the connections between schedule, queue and Jobs in Laravel/Lumen?
