Answer 1

You will need offline_access.

Enables your app to perform authorized requests on behalf of the user
at any time. By default, most access tokens expire after a short time
period to ensure applications only make requests on behalf of the user
when the are actively using the application. This permission makes the
access token returned by our OAuth endpoint long-lived.
