Unable to create complication app id

In the WWDC2020 "Keep your complications up to date" session, Mike shows that you have to create an App ID that ends with ".watchkitapp.complication" in order to support PushKit. Any time I try to add ".complication" to the end of my App ID, it gives an error:

An App ID with Identifier 'com.x.y.watchkitapp.complication' is not available. Please enter a different string.

You only need the .complication for the push topic. Any other place where you are asked for the app ID should not have the addition of .complication.
