Hello !  Regarding android permissions since Android 6 users can decide to denied and check "never ask again" for a permission you asked. This is even more relevant with Android 11, which is the solution by default when user deny your permission. I saw on some apps, that they are able to ask for a permission and if it's denied (at runtime or even before the app is started) they open the settings app, and the user can enable the permission from there. I haven't seen any official documentation for this specific behaviour. How do they detect the permission has been fully denied (prompt can't be shown again) ?
Thanks !

Usually it's done by requesting the permission, getting `PERMISSION_DENIED` then calling `.shouldShowRequestPermissionRationale()` which will tell you if it is acceptable for you to tell the user why the permission is needed. Note that method will return `false` if you have never requested the permission - you have to have requested it and it been denied before it will return `true`.

oh thanks, I saw the API `shouldShowRequestPermissionRationale` on the official documentation but it wasn't clear that it will return `true`  if the permission was already asked.
