Next, we need to sync videos using our API client which we'll do with a higher level abstraction to integrate with the API.
Now that we can sync videos to our local database, we need to run this on a regular schedule. We'll use SolidQueue's recurring tasks feature to create cron jobs that run periodically for syncing.
