 === Customize the ID Token
 
 By default, the user info response is generated by using claims from the `id_token` that are returned with the xref:{docs-dir}/protocol-endpoints.adoc#oauth2-token-endpoint[token response].
 Using the default strategy, https://openid.net/specs/openid-connect-core-1_0.html#StandardClaims[standard claims] are returned only with the user info response based on the https://openid.net/specs/openid-connect-core-1_0.html#ScopeClaims[requested scopes] during authorization.
