Notification filtering entitlement not working on iOS 13

I'm running an app with the com.apple.developer.usernotifications.filtering entitlement and the filtering works fine with iOS 15.

However I tried running it on an older phone / OS (iPhone 8 / iOS 13.1.2) and it does not work.

Is this entitlement not supported with iOS 13.1.2? If so, what is the earliest iOS version that supports it?

The handset logged this:

The OS displayed: default 07:55:58.800825-0800 NotificationServiceExtension   Mutated notification request will not visibly alert the user, will deliver original content

If the app is run on iOS 15, it says :

default 07:20:27.251600-0800  SpringBoard        Mutated notification request will not visibly alert the user, will supress original content

This isn’t really my field but…

Is this entitlement not supported with iOS 13.1.2?

The entitlement’s documentation says that this is supported on iOS 13.3 and later.
