[SOLVED] Kotlin Multiplateform-Unable to find explicit activity class "android.content.ActivityNotFoundException"

I am using Google App Actions to run and test my custom intent on my existing Kotlin Multiplatform (KMP) project. The problem is that whenever we run the app action from the Google Assistant plugin, it will not find the activity class. error logs:

startActivityAsUser: callingPid=7402, callingUid=10225, caller=com.android.server.wm.ActivityTaskManagerService.startActivityAsUser:1816 com.android.server.wm.ActivityTaskManagerService.startActivity:1767 android.app.IActivityTaskManager$Stub.onTransact:1244 com.android.server.wm.ActivityTaskManagerService.onTransact:6590 android.os.Binder.execTransactInternal:1316 android.os.Binder.execTransact:1280 <bottom of call stack>

    android.content.ActivityNotFoundException: Unable to find explicit activity class {au.com.packagename.app.android/au.com.packagename.app.android.MainActivity}; have you declared this activity in your AndroidManifest.xml, or does your intent not match its declared <intent-filter>?

I had tried this on a separate sample KMP project, and everything works fine there with the same custom intent. I am not sure if this is an issue with some setting in the KMP project or something else.

Here is my AndroidManifest.xml

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
