Hi Boris Hubner,
Thank you for reaching out to us on the Microsoft Q&A forum.
We have reached out internally to make the necessary changes, and it will reflect soon.
Meanwhile in the exercise you're working on, the instructions clearly state that you should use PowerShell (or pwsh) from your local environment in Visual Studio Code to deploy the template. If PowerShell is already selected in your terminal, you can continue without switching to another shell.
The reference to Azure Cloud Shell (PowerShell) in the instructions may have caused some confusion. For this task, there's no need to use Azure Cloud Shell (PowerShell)—just make sure your local PowerShell (or pwsh) terminal is active. This should resolve any issues, allowing you to proceed with the deployment as instructed.
Please don't hesitate to reach out to us if you have any other queries.
If you found the information helpful, we would greatly appreciate it if you could acknowledge it by selecting the Accept Answer & Upvote options.
