We are developing an application, in that we need to get all the files of all users in the domain. We have enabled service account with domain-wide delegation already, but whenever we tried to access all user's drive, it is required to get each user access token separately after setting each user id using google credential object method (e.g. googleCredentialBuilder.setServiceAccountUser({email_id})). We are using Drive API client library for Java and admin SDK for getting all the users in the domain.
So, our concern is to get all users to drive files using a super admin access token. Is there any alternate way to get all users to drive files using domain/admin-level access token. Kindly help me in this regard.
