Voila + reveal.js: select different reveal.js template?

JupyterLab
1

I recently started preparing a talk with the reveal.js template option to voila/voici and absolute love it. However, by default this uses the “white” template of reveal.js, but other options can be found here: Themes | reveal.js. How do I configure voila to use e.g. the “blood” template when I run the command

voila mynotebook.ipynb --template=reveal

Either a command line command or instructions on how to construct a config json file would be very much appreciated. I’m still struggling with understanding how to configure jupyterlab/voila in general. I tried to follow the generic instructions in the documentation but that didn’t help me to set such specific options.

I have an example that works with Voila to set things to show tracebacks here. You may also be able to/need to call it voila.json, see here. Where I am referencing is a modified JupyterHub and so I am following the details here in that example I referenced.
I don’t think I have a version setting a theme though as an example.
