title: GAS/clasp: How do I get autocomplete/intellisense to work in VSCode for 3rd Party libraries
body: <p>I am using VSCode to edit Google App Script (GAS) code with clasp.
  I have intellisense working for the core libraries just fine.</p>
  
  <p>(This <a href="https://stackoverflow.com/questions/49015874/enabling-autocomplete-for-google-apps-script-in-locally-installed-ide">post</a> helped)</p>
  
  <p>However, I am also using a <a href="https://github.com/grahamearley/FirestoreGoogleAppsScript" rel="nofollow noreferrer">Firestore library</a> in the ScriptApp project and intellisense is not working for the FirestoreApp.</p>
  
  <p>I've tried included the library Javascript code in my project directory and also in the node_modules directory - but no luck.</p>
  
  <p>Does anyone have any tips? Thanks.</p>
