Settings for inline menu item suggestions added with v8.12.8

The release notes for 1Password in the browser 8.12.8 include this nugget:

We’ve added settings that let you choose which item types appear as autofill suggestions in the inline menu. (#FS-4508)

Sounds like a very useful feature, but having searched through the settings areas of both the browser plugin and the 1P app, and even in the inline menu itself, I see no such inline menu options. Where do I find this new feature?
