Description:
Any attempt to Add the Google Drive Service via OPEN REMOTE or SAVE REMOTE to Google Drive results in a demand for a six-digit PIN. I don't have 2FA.
I have tried to access both my genuine account and a "fake" and regardless of the validity of the account credentials, Libre still demands a non-existent code.

Steps to Reproduce:
Libre CALC
File > open remote
Try to activate the Google drive service for the first time using valid account data for an account that does not utilise 2FA. See the attached screen image.
Try to activate the Google drive service for a subsequent attempt using fake account data which by definition cannot have 2FA. See the attached screen image.
Only one screen image because the results are identical
Try any random 6 digit number to satisfy the request  or not - as desired.


Actual Results:
Failure to ascertain the desirability of requesting a 2FA code nor create or access a Google drive remote service

Expected Results:
Query the user as to the validity of 2FA and take appropriate steps to create the service when 2FA is not a feature of the Google Drive account or desired by the user.


Reproducible: Always
