Can't find section to use own stylesheet

Hi everyone

In the FAQ, it says:

“When you go into the Ajax Edit Comments settings page, you’ll see a section called “Styles”. From there, you’ll be able to enter a “relative” URL to a stylesheet of your choice, which will override the styles provided by Ajax Edit Comments.”

I can’t find a “styles” section in any of the AEC settings pages. Can anyone tell me where it is?

Thanks!
