Pre-requisites:
Add Google Play Core lib to your app.gradle's dependency list

app/App_Resources/Android/app.gradle ->

dependencies {
  ...
  implementation 'com.google.android.play:core:1.8.0'
  ...
}

and just call the function below. The review dialog won't show up unless the
app was installed from google play
