Research and implement push notifications for React Native with Elixir backend

[mdshamoon]

Is your feature request related to a problem? Please describe.
At some point we will need to send push notifications on the app for various things like errors or events happening

Describe the solution you'd like

• When a notification is send from the server it shows notification bar on the mobile even if the app is not open
• Research on how we can do this with an elixir backend

@mdshamoon I would like to work on this issue. Please assign it to me?

We can use expo notification: https://docs.expo.dev/push-notifications/sending-notifications/

But in this approach, there will be an intermediate Expo backend that we may not want?

[mdshamoon]

We definitely don't want the expo backend.
Just check these and see if it can work for us:

@mdshamoon I have implemented the code in the Elixir backend, which have two end point

1. register the user's device token and device type, and
2. send push notifications directly to any device using FCM and APN.

However, the problem is occurring on the frontend side. Actually, Expo is restricting us for using the Expo Notification package, which relies on Expo Server as an intermediate server. This is because, for direct implementation with FCM and APN, several configurations need to be done in different native files of Android and iOS, which are only available in a React Native CLI project.
