Is your feature request related to a problem? Please describe.
We are using Sagemaker Studio for most of our usecase and would like to use Graph notebooks as well in the Studio. The new version of Sagemaker Studio comes with Jupyterlab v4 as default and from the install documentation for the graph-notebook it is expecting Jupyterlab v3 as in link. We would like to continue using Studio for all our notebook usecases, we are aware that there is a graph notebook possibility using the classic Sagemaker notebook but we don't want to go that way as Studio has better user authentication or other features we depend a lot on.

Describe the solution you'd like
We would like to see graph-notebooks being supported in Jupyterlab v4 as well.
