title: Adding share action in React Native
body: <p>Trying to build a React Native app that <strong>injects a menu item in the Share menu</strong> (Share Action for Android, Share Extension for iOS). Is there a component for this, and if not what's the best way to build one?</p>
  
  <p>I don't need to create ActionSheet in my app, i need to <strong>injects a menu item in the Share menu</strong> to allow users share urls from browser to my app.</p>
