LoginWithTheBackendToken

public BackendReturnObject LoginWithTheBackendToken();

Description

User who logged in before tries to log in using a BACKND AccessToken stored in the device locally.
BACKND SDK's login method requires an unexpired access_token or refresh_token stored in the device.
When the login succeeds, access_token and refresh_token are updated with new ones.

});
