Here's what I suggest and what has worked for me. In your application class, implement an Application.ActivityLifeCycleCallbacks listener and set a variable in your application class. Then query the variable as needed.

class YourApplication: Application.ActivityLifeCycleCallbacks {
    
    var currentActivity: Activity? = null

    fun onCreate() {
        registerActivityLifecycleCallbacks(this)
    }

    ...
    
    override fun onActivityResumed(activity: Activity) {
        currentActivity = activity
    }
}
