Dear Jeroen
At present I am testing it, as per the instructions given, That is, after download, unzipped, renamed the folder to ‘jupyter’ and then copied the entire folder to plugins folder of the home path, i.e. not in the program files path. Then, opened Texmacs, did tools=>update=>plugins. Then restarted Texmacs.
This time jupyter plugin started showing as Insert => Session =>Jupyter=>default as one option and the other option as Insert => Session =>Jupyter=>Python was not found; run without arguments to install from the Microsoft Store, or disable this shortcut from Settings > Manage App Execution Aliases.
I chose both options one by one and in both cases, and the results were still the same, see the copied output below:

Jupyter]
Let me inform you that I have both Python 3.11.3 and the latest JuypterLab installed. In the latter, IR kernel is showing and working. But, why I don’t like either Jupyter Notebook, Jupyter Notebook and Rmarkdown, because both follow markdown for wirting text materials, other than the R codes, which is very clumsy, and NOT as per the standards of a good typeset article or book. I liked the same in TeXmacs, but here I am suffering from problems with R plugins.
Still, I hope you would be able to do something real good.
With regards,
Dr. A.K. Singh
