Jupyterlite sphinx kernel not appearing

[Tom_Pike]

I am integrating jupyterlite-sphinx into mesa-geo readthedocs. I have the jupyterlite instance to appear but cannot get the kernel

Intro Tutorial

I have

• Installed Xeus-python
• Added jupyterlite_contents to my conf.py
• Added jupyterlite_build_command_options with XeusAddon to my conf.py

I also tried adding a jupyterlite_environment.yml file to the docs folder but it had no impact.

This builds but I cannot get a kernel to show up.
