Trying to follow along with the instructions for the 'AWS and Databricks' training yet the documentation gives no indication of how to access the workspace that is ostensibly generated in AWS. I subscribed through the marketplace and cloud formation ran...... now what? Following instructions here: https://databricks.com/p/thank-you/webinar-databricks-on-aws-3-part-training-series-140125 there is no indication of how to actually launch the workspace once subscribed.
