NSNearbyInteractionAllowOnceUsageDescription Key no longer exists?

I'm attempting to upload a sample Nearby Interaction app to Testflight so others on my team can test. When I submit the app, I get an email from the Apple saying this: "Missing Purpose String in Info.plist - Your app's code references one or more APIs that access sensitive user data. The app's Info.plist file should contain a NSNearbyInteractionAllowOnceUsageDescription key...". In Xcode 13, this key does not seem to be available under Custom iOS Target Properties. I have the Deployment set to iOS 15. Reading here, https://developer.apple.com/documentation/bundleresources/information_property_list/nsnearbyinteractionallowonceusagedescription, it says the above key is Deprecated and to use NSNearbyInteractionUsageDescription, which I have done but still get the submission error. Any help would be appreciated!
