Is there a way to add more scopes to the authorization

[himaja0726]

Using the below code we provide the scopes. In the below code I added scope for mail. Is it possible for me to add more scopes to the current authState. Say I want to add calendar scope later to the existing authState. How should I do it.

[[OIDAuthorizationRequest alloc] initWithConfiguration:configuration
clientId:kClientID
clientSecret:kClientSecret
scopes:@[OIDScopeOpenID, OIDScopeProfile, @"https://mail.google.com/"]
redirectURL:redirectURI
responseType:OIDResponseTypeCode
additionalParameters:nil];
