@Sanjay Jain In the data explorer, you can just see the object level information. If you need the version history of each delta lake table, the below command would help
DESCRIBE HISTORY table_name
If you need to see each notebook level versioning, you can look in the UI itself. This will help to see the changes in each version of your notebook and revert back to any previous versions. But if your requirement is on a complete workspace level, then using Version Control tools like Git or Bitbucket should help.
Please check the below links for some more idea on this.
