feat: add ability to request the device token without showing permission

[gtokman]

Description

Right now the only way to get the device token is to go through the permission prompt. This is not ideal if you want to support silent notification w/o asking for permission. This update allows you to achieve this.

Docs

If you want your app’s remote notifications to display alerts, play sounds, or perform other user-facing actions, you must request authorization to do so using the requestAuthorization(options:completionHandler:) method of UNUserNotificationCenter. If you do not request and receive authorization for your app's interactions, the system delivers all remote notifications to your app silently.

That's a good addition, and I require this functionality. Do you have any updates regarding this?

@yousrasd Alternatively you can throw this in your AppDelegate:

UIApplication.shared.registerForRemoteNotifications()
