I'm confused about what this repository is and how I would use this or who would use this. I see that GroundControlToMajorTom talks to both Apple (https://api.push.apple.com) and Google (https://fcm.googleapis.com) push servers.

Thus, it seems that this is the infrastructure component that tells the Apple and Google servers what devices to ping if something relevant to the user's wallets happens.

However, I doubt that I can just run this to ping a device that runs the official build of BlueWallet? I assume Apple/Google would want to see some certificate to make sure that only the BlueWallet team can ping devices? How would I populate the stuff below?

FCM_SERVER_KEY hex encoded
APNS_PEM hex encoded
APNS_TOPIC for example io.bluewallet.bluewallet
