Need to restart jupyter server frequently

[nileshvd]

Tested in SageMaker JupyterLab

Installed the extension, and kept the tab open. After some time (most likely after some kind of session timeout) S3 browser stopped showing S3 contents. Restarting jupyter server fixes the issue, but this should not be necessary

Expected
No need to restart jupyter server

I think this is caused by session token being generated when the jupyter server starts and that it never gets refreshed. Reference: https://github.com/QuantStack/jupyter-drives/blob/main/jupyter_drives/base.py#L76
