I am using VSCode to edit Google App Script (GAS) code with clasp. I have intellisense working for the core libraries just fine.
(This post helped)
However, I am also using a Firestore library in the ScriptApp project and intellisense is not working for the FirestoreApp.
I've tried included the library Javascript code in my project directory and also in the node_modules directory - but no luck.
Does anyone have any tips? Thanks.
