Notification Service Extensions in App Clips

Xcode is not allowing me to install an App Clip that includes an embedded Notification Service Extension. This means that there is no way to add media attachments to remote push notifications.

My company had a 1:1 session with an App Clip expert for WWDC and they claimed that Notification Service Extensions were supported but it seems they were wrong. Is this a bug or is it intended that Notification Service Extensions are not supported by App Clips?

Xcode install error message:
Unable to install "TestAppClip"

This app clip has at least one active plugin. App clips aren't allowed to contain any active plugins.

App Clips do not currently support app extensions and subsequently do not support Notification Service Extensions. I encourage you to file a feedback assistant report for your use cases!
