Implementing A Direct Link to App Settings

Howdy, I have a ***** feeling that the answer to my question is "Y'all cain't do that!", but I figure I'll ask, anyway.

THE SAD STORY (GET YOUR HANKY):

We have an app that implements Sign [up|in] with Apple. It does it pretty well, with no password visible to the user, and a pretty smooth UX.

The issue is what happens when users bork their install. We don't think it will happen often, but want to be able to give the user the best way out, if possible.

With the regular (non-SiiA) method, they bonk on a "Forgot Password" button, and the app sends them a new password.

We can't do that, with SiiA. The password is stored in the app (in the keychain, so it's very persistent, and shared across devices), and it would a Very Bad Security Hole, to allow users to simply send a new password to the server (the other method generates a rando in the server), which is what would happen, with our method of handling the password. It would also be equally bad, if the server could simply send a new password to the user, directly to their device (the other method sends an email, based on the sign-in information on the server).

So the user needs to delete their keychain data completely, which we can easily do, but that does not deal with their SiiA stuff, stored on Apple's server.

This is what Apple tells us to do, to delete that.

WHICH BEGS THE QUESTION:

My question is: Is there a URL scheme that I can use to directly open that panel?

If so, it would allow us to create a screen that helps the user to do all the deletions (on the device, our server, and the Apple server).
