Do App Intent Domains work with Siri already?

Hi, guys. I'm writing about Apple Intelligence and I reached the point I have to explain App Intent Domains

https://developer.apple.com/documentation/AppIntents/app-intent-domains

but I noticed that there is a note explaining that these services are not available with Siri. I tried the example provided by Apple at

https://developer.apple.com/documentation/AppIntents/making-your-app-s-functionality-available-to-siri

and I can only make the intents work from the Shortcuts App, but not from Siri.

Is this correct. App Intent Domains are still not available with Siri?

Thanks
