Issue description
You do not see the Table of Contents extension in the JupyterLab extension catalog in your DataSphere project running in the Serverless mode.
This extension facilitates navigation inside the project files using headers.
Solution
In the serverless DataSphere mode, JupyterLab 3.X isn't available yet.
You can use the Dedicated mode where JupyterLab 3.5.3 is available.
Follow new DataSphere releases on the changelog page in the documentation.
