Using JupyterLab 3.6.1 and Voila 0.4.0

I pip installed JupyterLab 3.6.1. The install also automatically installed a few dependency Python packages, including jupyter-server version 2.3.0 and jupyter_client version 8.0.3. I want to use voila dashboard, so I pip installed voila version 0.4.0 (latest stable), which requires lower version of jupyter-server 1.23.6 and jupyter_client 7.4.1.

When I start JuptyerLab, it then throws the following error:
ServerApp] jupyter_server_terminals | error adding extension (enabled: True): Jupyter Server Terminals requires Jupyter Server 2.0+

With this error message, what JupyterLab functionalities will I lose? Thanks!
