Opening up Siri prefs from an app

In our onboarding sequence we inform the user that Siri is required and to set it up if they have it off. We have a link that takes us to the root of the Systems tree, but have been unable to get it to launch into the Siri prefs itself, using a scheme that's widely available on StackOverflow, GitHub and so on.

ChatGPT says it can't be done as of 2022. I see a list on GitHub of the domains that was last updated just a year ago, suggesting that at least as of 17 it "should" work.

Another place said Apple would bounce apps which attempt to do that (we have the recommended URL string already in there which should have been detectable by their scans, and have not been bounced due to that so far).
