How to launch built-in/first party applications using c# in Unity project (for both Android and iOS)?

I am looking for an approach that allows me to launch the first party apps (e.g. notes, calendar, reminder, calculator, etc.) from both iOS and Android from my Unity project. I have done some research online and found some examples that open third party apps from Unity games, which don't fit for my case. (e.g.https://forum.unity3d.com/threads/android-ios-launch-from-within-a-unity-app-another-unity-app.222709/)

Please give me a hand if you have done similar features before. Appreciate!
