deployment via xcodebuild command line utils: How to add release notes?

I am deploying to testflight using xcodebuild command line tools. How to add release notes? I am using following command.

xcodebuild -exportArchive -archivePath $PWD/build/app.xcarchive -exportOptionsPlist ./exportOptions.plist

I need testers to be able to see notes under "What to test" section in testflight.

You will need to upload the "what to test" info separately using the App Store Connect API. (Or just use the website.)
