Firebase In-App Messaging showing in SplashActivity. How to show it in MainActivity?

I have enabled Firebase In-App messaging for my android app. When i am testing In-App Messaging it is showing in SplashActivity of the app.

Activity flows like: SplashActivity>LoginActivity>MainActivity

Note: SplashActivity just have runnable to get delay of 3 seconds. LoginActivity have some functions to check wheter shared preferences are not null.

I tried to add in onCreate() this below line of code: FirebaseInAppMessaging.getInstance().setMessagesSuppressed(true)

And FirebaseInAppMessaging.getInstance().setMessagesSuppressed(false) in onDestroy()

I want this messsage to show in MainActivity.

Firebase in-app messaging is triggered by analytical events.

if you want show message in MainActivity ->

class MainActivity : AppCompatActivity() { 
override fun onCreate(savedInstanceState: Bundle?) {
    super.onCreate(savedInstanceState)
    ...
    FirebaseAnalytics.getInstance(this).logEvent("main_activity_ready",null)
    //or 
    //FirebaseInAppMessaging.getInstance().triggerEvent("main_activity_ready");

}
}

and select this event in firebase console.
