If you are not using the native bottom navigation in your app, you might still want to open the "Settings" screen, where users can easily adjust their push notification settings.
You can integrate website elements with the app for this, using native functions.
Here is a simple code sample that shows how you can achieve this:
<a onClick="nativeFunctions.settingsOpen();">Open Settings Screen</a>Since native functions will only work in the app, you might want to wrap your web element with a conditional, so it only shows up in the app.
