Google API의 InsufficientCredentials

이 오류가 무엇인지 이해하려고합니다.

  File "C:\...\googleapiclient\http.py", line 856, in execute
    raise HttpError(resp, content, uri=self.uri)
googleapiclient.errors.HttpError: <HttpError 403 when requesting https://www.googleapis.com/drive/v3/files/19XYXTA2xER982xIHnDqH0cOtjBtSZtgC?alt=media returned "Insufficient Permission: Request had insufficient authentication scopes.">

"권한 부족 : 요청에 인증 범위가 부족합니다."는 무엇입니까? 평균?
