/**
 * NOTE: When loading ExternalAccounts for use in an authentication context
 * (that is, you're going to act as the account or link identities or anything
 * like that) you should require CAN_EDIT capability even if you aren't actually
 * editing the ExternalAccount.
 *
 * ExternalAccounts have a permissive CAN_VIEW policy (like users) because they
 * interact directly with objects and can leave comments, sign documents, etc.
 * However, CAN_EDIT is restricted to users who own the accounts.
