disable the Clear Data button in android applications settings- manageSpaceActivity not working in unity

Question

I'm working on an android game in Unity game engine. I want to disable Clear Data button in Android's Application Info of Manage Application to prevent user from clearing the application's data. In Android Studio I use manageSpaceActivity in the Manifest.xml file and it works fine.

<application ... android:manageSpaceActivity=".ManageSpaceActivity">

But in unity when I add this code to [ProjectName]/Assets/Plugins/Android/AndroidManifest.xml it does not work. So, my question is where should I add android:manageSpaceActivity=".ManageSpaceActivity" in unity's AndroidManifest.xml file?
