IssueTracker

Since Jupyter Lab 4 Vertex AI instances are still in preview, the mount option is not available, as in [1].

A good addition would be to also include this information to the documentation [2], since it can get confusing why the button still does not show up, even after adding the necessary roles.

Could you please mention in the documentation [2] that a possible cause of the button not appearing is that the instance uses Jupyter Lab 4?
