itkwidgets error in Jupyter Notebook

I'm trying to set up Jupyter Lab (4.0.11) environment for mayavi 4.8.1 on a remote server.

First of all, I note that
```python
%env QT_QPA_PLATFORM=offscreen
```
should be set before importing `mlab`. Otherwise importing `mlab` crashes. Then
```python
from mayavi import mlab
mlab.init_notebook('itk')
```
runs fine. However
```python
s = mlab.test_plot3d()
s
```
gives the following error messages depending on the installation method:

1. `conda install -c conda-forge itkwidgets` which installs `itkwidgets=0.32.6`

```

There is already report on the same problem https://github.com/enthought/mayavi/issues/1202#issue-1531272998 without any solution.
And I encountered the same error even in my laptop (MacBook Pro).

How do I obtain desired behavior of mayavi with itkwidgets?

Thanks in advance.

Start by reproducing the reported Jupyter Lab 4.0.11 setup with Mayavi 4.8.1 and the two itkwidgets installation methods. Read mayavi/tools/notebook.py, especially ITKBackend.display, alongside the shown itkwidgets viewer traceback. Done means mlab.test_plot3d() displays successfully through mlab.init_notebook('itk') without the reported widget or viewer errors.
