How to fix ipywidgets when they are not rendered in a jupyter-lab notbook?

I have jupyter-lab version 3.6.3 installed and it fails to render ipywidgets. I followed the instructions mentioned in their documentation and it still does not render.

These are the steps I've taken:

conda install -n base -c conda-forge widgetsnbextension
conda install -n test_env -c conda-forge ipywidgets

I run the jupyter-lab in the base env from the terminal and then select the test_env as for my kernel when the notebook loads. Then I run the following cell:

from IPython.display import display
import ipywidgets as widgets

w = widgets.IntSlider()
display(w)

And it outputs:

IntSlider(value=0)

I have restarted the jupyter-lab process multiple times to make sure the changes are in effect. And still, no luck.

Any suggestions?

If anyone else faced the same problem, these additional steps fixed the problem for me:

sudo jupyter nbextension enable --py widgetsnbextension --sys-prefix

And

sudo jupyter labextension install @jupyter-widgets/jupyterlab-manager
