Laravel pushing jobs into different queue with low priority

Right now I am using Beanstalkd and Laravel forge for my queues which I fire like this: dispatch(new ProcessPodcast($podcast));

But how do I push a queue into a different job that has a low priority? This will only push the queue into a different job but not set the priority: $job = (new ProcessPodcast($podcast))->onQueue('processing'); dispatch($job);

And if a queue job has a low priority does it mean that it will be fired later when there arent that many queues or how does low priority jobs work?
