This is my google drive file choose api code.
when I tried to run this code showing me error like DriveApp is not defined.
In this code I am getting error on that particular part:
function getOAuthToken() {
DriveApp.getRootFolder();
return ScriptApp.getOAuthToken();
}
I am referring the google documentation but still I am getting those error. https://developers.google.com/picker/docs/
