title: Enable/Disable firebase push notifications in react native app
body: <p>I have a react app with settings screens which allows to disable all types of notifications. How to achieve this wasn't exactly clear in <a href="https://v5.rnfirebase.io/docs/v5.x.x/" rel="noreferrer">react native documentation</a>. I can ask for user permission when he signup but how do I disable this permission from settings screen so he will not receive any notifications but user can enable them again in future.</p>
  
  <p>I can do this using topics but that's pretty limited. I want to target using audience from firebase console. 
  Any help appreciated.</p>
