Load Google Play Popup during Unity startup on Android?

Is it possible to load Google Play user authenitcation during Unity startup?

example without unity logo

I’m currently using the following code to authenticate the player:

void Awake()
{
	PlayGamesPlatform.Activate ();
}

void Start()
{
	// authenticate user:
	Social.localUser.Authenticate((bool success) => {
		
	});
}

But the code only runs after the Unity logo icon (startup)
