I need to create a new lab based on my repo templates. the lab should go to the power bi service, create a workspace, upload a pbix file, explore the published reports iwthin the workspace, and then create an app to include the report and create sections, and then create different audiences before publishign the app, then open the new app link and show the differences than opening the report link directly. also show how to share a report with a link before creating the app.
