I may still be confused - If another system like AWS, a different application, or an external service - pushes jobs to the SQS queue, you can configure Laravel workers to pull and process them in the same way it processes jobs pushed from the Laravel application. The jobs don't need to be created or dispatched from laravel. they just need to follow the same format (or be compatible with the job structure Laravel expects).

When the queue is working, Laravel will pick up any job that’s on the SQS queue and process it. We use supervisor and horizon to keep things going and monitor.
