OKDemoScene.cs
score.submitScore((success, errorMessage) => {
if (success) {
Debug.Log("Score submitted successfully!");
} else {
Debug.Log("Score did not submit. Error: " + errorMessage);
}

should be like?
score.SubmitScore((success, errorMessage) => {
if (success !=null) {
Debug.Log("Score submitted successfully!");
} else {
Debug.Log("Score did not submit. Error: " + errorMessage);
}
