Push translated from English, means push, boost[...]. Already Notification, is notification, communication, warning[...]. Joining the two words, we have as an example "boost notification". The main objective of the Push Notification is to shorten the path between the sender and the receiver
The purpose is not to traffic a large mass of data, but to send simple messages, for example, to warn that there is a new data to be downloaded from the server, or to show some kind of store promotion, system update, etc.
According to a survey by Urban Airship, daily use of an app increases by up to 540% with sending these notifications.
Nowadays using Push Notification has become much easier using the Firebase Cloud Messaging. See more details in the documentation. Here too in the documentation of Xamarin also has a Quickstart explaining and explaining how FCM works.
It is possible to create a solution to your problem through both the Push Notification how much Pull Notificationen. The difference is that Pull checks if there is any update on the server, while the Push will notify the user when there is any update. For your case maybe, say perhaps, the most viable way would be using the Push Notification, as it will avoid creating service for refresh check from time to time. The clearest way to use the Pull Notification is when you store some kind of data on smartphone, I say on the client side, where, through a particular analysis of local data, you make a request to the server in a manner directed to that client.
Yeah, that’s the whole concept of push notification. The information is pushed into the app, the app doesn’t pull it

I’m having a lot of trouble implementing. It’s not working with me and I’ve already opened another post on the subject. I was in doubt and came here to ask if what I really want is Pushnotification or if there is another way to do it, @Jeffersonquesado.

Sorry for the words, but it’s really a hindrance to make a push notification. You are usually at the mercy of some third-party framework, such as Firebase that is described in the @acklay response
