AppSheet App to receive permission to access 3rd party GDrive account

Hi,
question, how is the way to have 3rd-party to grant access to an 2nd-party operator of my AppSheet app for the 3rd-party GDrive account ?

I’m not looking for the share files function from GDrive where the operator then would receive shared files in their shared files folder.

My AppSheet app is to use access under a certain directory which is created and managed by my app.

Regards,
Frank
