Handle InSendMessageIntent in the app

Hi, I'm implementing InSendMessageIntent handling in our app. I can handle InSendMessageIntent through extension, but handling also includes business logic like authorisation status and some heavy operation which I can't expose from the main target. I tried to handle it in-app, but func application(_ application: UIApplication, handlerFor intent: INIntent) -> Any? didn't trigger. At the first glance the configuration looks correct - the InSendMessageIntent is added under INIntentsSupported and UIApplicationSupportsMultipleScenes is set to YES in info.plist.

After that reply with message button disappeared from the incoming Voip callKit screen.

So I had a question - Is this intent possible to be handled in-app?
