This is an optimization.
On Android, iOS and ChromeOS, OAuth multilogin requires access tokens.
However, on desktop platforms, we may use refresh tokens directly, and thus skip the access token requests.
Note that refresh tokens are currently not exposed outside of the token service, so this will require changes in the token service to either expose them or have the token service somehow make the multilogin request.
