Should this PR be rebooted using the extension upgrade script? https://jupyterlab.readthedocs.io/en/latest/extension/extension_migration.html#upgrading-extension-using-the-upgrade-script

This would help pick up the latest changes to the extension template.

Which versions do you need, the latest of each?
