I would like to develop a Google OAUTH2 Application that requests permission from my service accounts (email inboxes) and then stores there OAUTH2 token to my Firebase DB or Local DB.
The scopes required are:
[login to view URL] Read, compose, send, and permanently delete all your email from Gmail
[login to view URL] Manage drafts and send emails
[login to view URL] Insert mail into your mailbox
[login to view URL] Manage mailbox labels
[login to view URL] View your email message metadata such as labels and headers, but not the email body
[login to view URL] View and modify but not delete your email
[login to view URL] View your email messages and settings
[login to view URL] Send email on your behalf
[login to view URL] Manage your basic mail settings
[login to view URL] Manage your sensitive mail settings, including who can manage your mail
Warning: This job must be completed within 24 hours.
