Using Adafruit's I2S Speaker Bonnet setup with Mopidy/Musicbox

I’m in the settings.ini file, and I see that I2S cards have to be explicitly set. It has several examples there, but I’m using Adafruit’s I2S bonnet for Pi Zero (https://www.adafruit.com/product/3346), and it’s not there. I’m pretty new to this, and I really don’t want to mess this up, so what do I need to set output to?

Thanks in advance.

Anybody? My project is on hold until I get this sorted out.

Well, the instructions on their sales page say it uses the phatdac driver so my suggestion would be to select that in pimusicbox.
