localization: "Include Screenshots" grayed out

I'm following along with "Creating Great Localized Experiences with Xcode 11" from WWDC 2019.


My test run generated a lot of screenshot attachments which I can see in the test results.


However, in the "Export for Localization..." dialog "Include Screenshots" is grayed out.


What sort of configuration is required to get this to work?

Have you tried any setup in your application scheme settings under Test? You must change it to add the .xctestplan file.
