Do I need to be a registered iOS developer to test push notifications through firebase?

Question

iOS

Good afternoon!
The problem is the following. Not being a registered iOS developer yet, I am conducting, so to speak, experiments with the application in order to understand whether it makes sense to develop the idea further. Accordingly, I postpone the moment of registration and the entry of money to the last moment.
However, I encountered the following problem when connecting the react-native application to Firebase:
- On the simulator, the registration of the application in firebase according to their instructions is successful and I receive a token. Notifications, however, do not come, but this, as I understand it, is due to the lack of a Firebase connection to APNS, which can only be done after registering with the Apple Developer Program
- On a live device, even getting a token in Firebase breaks off. messaging.gettoken() says you must be registered for remote messages. It seems that everything was done according to the instructions, AppDelegate.m was modified to support Firebase. But, the question is, maybe I’m using all the recipes from stackoverflow in vain and for a successful connection, you must first register in the Apple Developer Program, acquire all kinds of certificates in xCode, and only then will Firebase be able to work?
