I want my react-native app to share a photo with Instagram. I know it\'s possible when writing in native code to open up Instagram\'s filter screen with a specified photo.

Here is how you post

import { CameraRoll } from 'react-native'

callThisFunction = async () => {
      await CameraRoll.saveToCameraRoll("https://images.unsplash.com/photo-1504807417934-b7fdec306bfd?ixlib=rb-1.2.1&ixid=eyJhcHBfaWQiOjEyMDd9&w=1000&q=80", 'photo');
      let instagramURL = `instagram://library?AssetPath=null`;
      Linking.openURL(instagramURL);
  }
