I have finally learnt to install grive2 on my arch based linux , plasma

run Code:$grive -aand google slapped me with this!
All my efforts are in vain.

Code:This app is blocked

This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.
I have tried to unblock from inside google security setting, but there is just nothing to unblock.
