Can my phone receive Firebase push notification if I have installed an app that support it but I have never open it before

Question

Do I need to open the app at least once in order for my phone to receive a push notification?

The must run at least once so it can collect a device ID token and send that to the backend that will send the message. Without that token collected, the app can never receive a message on that device.

Actually you do not need the device token to send/receive the messages.

However, it is required that the user give permission to receive notifications, and that would only happen during runtime. I tested this and can confirm it works. The device token is only used to subscribe users to specific topics, but you can send a message to all users that have your app installed without needing to specify device tokens.
