Jupyter ipywidget 7.6.5 and voilà under Anaconda jupyter book default kernel does not display widget

I know that unfortunately Voilà doesn’t work yet with ipywidget 8.0
I worked with the 7.6.5 version, but it sill renders nothing. I downgraded to 7.6, and my output is not working well in the book but displays in voilà…

I didn’t see anything about not being compatible with version 7.6.5. Could someone point me out on some article to make it work?

Thanks in advance

This isn’t the case. See here for at least a couple reports of it working with ipywidgets 8.0.2.
