title: How to add sensitive values to Expo plugin configuration and build with eas-cli
body: <p>I'm using Expo to build a React Native app and recently implemented react-native-fbsdk-next for Facebook authentication, but I’m having trouble trying to hide sensitive values on it’s plugin configuration.</p>
  <p>What I did so far was to store those values in a <code>.env</code> file, install the dotenv library and import it on top of app.config.js. Everything works fine prebuilding the project locally but every time I try to build with eas-cli, I get an error that the appId (One of the propertys for plugin configuration) is missing.</p>
  <p>I created a secret for those values in my project configuration through expo dashboard site and expected it to work but the error persisted.</p>
  <p>Is it possible to hide sensitive values for plugin configuration or I’ll need to expose them ?</p>
