[Jupyterlab Widget] Error displaying widget: model not found

**Describe the bug**
I keep getting the message **Error displaying widget: model not found** - I've tried all the released versions and none of them run.

**To Reproduce**
Steps to reproduce the behavior:
1. install a clean new environment
2. install any available version of the keplergl python package (from pip or conda-forge)

**Expected behavior**
the demo script will run and draw something.

**Screenshots**

**Environment (I tried different versions of python, jupyter and keplergl, but it didn't work in any of them):**
- Python version: 3.8, 3.11, 3.12
- keplergl 0.3.4a3 pre-release, 0.3.4a2 pre-release, 0.3.2
- JupyterLab 3.5.3, 3.6.7, 3.6.8, 4.2.5
- Jupyter notebook 7.2.2
- Ipywidgets 7.8.4, 7.6, 8.1.5
- nodejs 10.19.0, 22.9.0

**Additional context**
Can you please give an example of a python/jupyterlab package version combination that successfully runs keplergl from the pip?
