I'm exploring whether serverless (https://docs.databricks.com/en/jobs/run-serverless-jobs.html#create-a-job-using-serverless-compute) could be useful for our use case. I'd like to see an example of using serverless via the API. The docs say "To learn about using the Jobs API to create and run jobs that use serverless compute, see Jobs in the REST API reference". But that's just reference info, not a tutorial. Is there any tutorial-style documentation showing how to start a job using serverless?
