+
+Updated the AuthApi `.create` methods to configure the default scope of the corresponding Auth Api. As a result the
+default scope is configurable when overwriting the Core Api in the app.
+
+```
+GithubAuth.create({
+  discoveryApi,
+  oauthRequestApi,
+  defaultScopes: ['read:user', 'repo'],
+}),
+```
+
+Replaced redundant CreateOptions of each Auth Api with the OAuthApiCreateOptions type.
+
+```
+export type OAuthApiCreateOptions = AuthApiCreateOptions & {
+  oauthRequestApi: OAuthRequestApi;
+  defaultScopes?: string[];
+};
+
+export type AuthApiCreateOptions = {
+  discoveryApi: DiscoveryApi;
+  environment?: string;
+  provider?: AuthProvider & { id: string };
+};
+```
