Closes #31

link2xt commented 6 months ago

Currently does not work because I tried to use API key from google-services.json as bearer token. This API key seems to be deprecated and only used in legacy API which is going to be removed in June 2024 according to https://firebase.google.com/docs/cloud-messaging/auth-server

https://firebase.google.com/docs/cloud-messaging/auth-server documents that new authentication happens via OAuth 2.0 and suggests using node.js, Python or Java SDK for this.

We need to use OAuth 2 without SDK, protocol is described here: https://developers.google.com/identity/protocols/oauth2/service-account
