Silent logout react native?

## Issue

I'm using Microsoft Azure ActiveDirectory for my mobile app and am attempting to achieve silent (promptless) logout. I've setup
a login_hint for my id token, but I'm unable to achieve a logout UX that prevents the popping of 2 dialogs - one for the user to acknowledge that the app wishes to use microsoftonline.com to Sign In and the second to choose the user to sign out.

Is promptless logout something that has been achieved with this library in react native?

In addition, the logout() method seems to log the user out as the Azure pop-up displays the message:

> You're signed out here, but you may need to manually sign out from other apps.

From here the pop-up dialog doesn't automatically dismiss, and I'm required to hit the 'Cancel' button in the top left
corner in order to dismiss the dialog. This results in the logout() method returning the following error:

`The operation couldn’t be completed. (org.openid.appauth.general error -3.)`

I suspect that this may be due to my postLogoutRedirectUrl, which is:

`'com.foo.mobile.unauth://oauth/'`

Is this supposed to be an https url? I used this form due to the need to use a similar redirect for login:

`'com.foo.mobile.auth://oauth/'`

Note, I have no issues with login. Everything returns successfully and the Azure dialog presents with a continue button for dismissing itself after successful auth.

## Environment

* **Azure Active**
* **Platform that you're experiencing the issue on**: `iOS`
* **Your `react-native` Version**: `0.71.4`
* **Your `react-native-app-auth` Version**: `7.2.0`
* **Are you using Expo?**: NO

Commencez par reproduire logout() sur iOS avec Azure Active Directory, en utilisant la postLogoutRedirectUrl signalée et la configuration de react-native-app-auth 7.2.0. Comparez la fermeture de la boîte de dialogue et l’erreur AppAuth renvoyée avec le flux de redirection de login réussi. Le travail est terminé lorsqu’il est déterminé si l’URL de redirection ou le flux de logout provoque les boîtes de dialogue et l’erreur, et qu’une résolution ou une limitation confirmée est documentée.
