Deep Links navigation in Jetpack Compose

I want to use deep links with Jetpack Compose's Nav Host and followed this page on Compose Navigation: https://developer.android.com/jetpack/compose/navigation#deeplinks

My implementation: AndroidManifest.xml:

<application ...>
    <activity
    ...
    android:allowTaskReparenting="true"
    android:launchMode="singleInstance">
        ...
        <intent-filter>
            <action android:name="android.intent.action.VIEW" />
            <category android:name="android.intent.category.DEFAULT" />
            <category android:name="android.intent.category.BROWSABLE" />
            <data android:scheme="https" android:host="xkcd.com" />
            <data android:scheme="https" android:host="www.xkcd.com" />
        </intent-filter>
    </activity>
</application>

MainActivity.onCreate().setContent{}

val rootUri = "https://www.xkcd.com"
NavHost(navController = navController, startDestination = "mainView") {
    composable("mainView", deepLinks = listOf(navDeepLink { uriPattern = rootUri })) {
        MainContent()
    }
    composable(
        route = "singleView/{number}",
        arguments = listOf(navArgument("number") { type = NavType.IntType }),
        deepLinks = listOf(navDeepLink { uriPattern = "$rootUri/{number}" })
    ) { backStackEntry ->
        val number = backStackEntry.arguments?.getInt("number")
        SingleView(number)
    }
}

If I now click on a corresponding link the app opens but the navigation doesn't work

The problem is with the Activity launchMode:

The documentation says that:

It is strongly recommended to always use the default launchMode of standard when using Navigation. When using standard launch mode, Navigation automatically handles deep links by calling handleDeepLink() to process any explicit or implicit deep links within the Intent. However, this does not happen automatically if the Activity is re-used when using an alternate launchMode such as singleTop. In this case, it is necessary to manually call handleDeepLink() in onNewIntent(), as shown in the following example:

override fun onNewIntent(intent: Intent?) {
    super.onNewIntent(intent)
    navController.handleDeepLink(intent)
}
