Hello Djonique,
Thanks for posting your question in the Microsoft Q&A forum.
The process for creating custom templates in Azure DevOps Demo Generator has changed with the release of version 2, which is now distributed as an executable application rather than a web-based tool.
The v2 executable is primarily designed for provisioning projects from existing templates. There is no documented or visible feature for extracting a custom template from an existing project in the current v2 executable
If you require a custom template and the extractor is unavailable, you may need to manually script the export of project artifacts, using Azure DevOps REST APIs, but this is a more complex and less supported approach.
