   The system creates a record in the Application Registries [oauth_entity] table with type OAuth Provider.
3. (Optional) Go to the related list on the record OAuth Entity Profiles to validate a system-generated default profile for the new OAuth provider without any scope.
   You can change or add an OAuth provider profile including the name, grant type, and OAuth Scope.
4. (Optional) Go to the related list on the record OAuth Entity Scopes to define all available OAuth scopes for this OAuth provider. You can select the scopes when you create or update a profile.
   Each OAuth scope contains a name and a scope that you must get from the provider's specification, such as a read scope or a write scope. Each scope must be defined separately.
