I must be missing something obvious. In the setup document, it refers to a "Google Project Number" for Google Play: https://documentation.onesignal.com/docs/corona-sdk-setup but I can't find it.
I went through the documentation and setup FireBase (https://documentation.onesignal.com/docs/generate-a-google-server-api-key), but don't see a Google Project Number. I also noticed that the Android native SDK's documentation sets the Google Project Number simply as "REMOTE" (https://documentation.onesignal.com/docs/android-sdk-setup). Is that what I should do? What should i be setting this to?
