resource

RFC8707: When requesting a token, the client can indicate the desired target service(s) where it intends to use that token by way of the resource parameter and can indicate the desired scope of the requested token using the scope parameter.

RFC8693: Optional URI that indicates the target service or resource where the client intends to use the requested security token. This enables the authorization server to apply policy as appropriate for the target, such as determining the type and content of the token to be issued or if and how the token is to be encrypted.
