There are two types of notebooks in Vertex-AI
1) managed notebook: https://cloud.google.com/vertex-ai/docs/workbench/managed/introduction
2) user-managed notebook: https://cloud.google.com/vertex-ai/docs/workbench/user-managed/introduction
I see that the former has a useful function called "idle shutdown" that help manage costs: managed notebooks instances shut down after being idle for a specific time period by default.
Why we didn't make it available for user-managed notebook as well? Thanks
