Native App with Okta scopes: unable to use Okta scope during authentication

I want to request an Okta scope (example:okta.users.read) using a native app so an admin can be restricted based on the scopes allowed.

If I try to authenticate against the default server, it claims that the scope is not one of the scopes for the server (however it won’t allow me to create scopes with the same name).

I thought it may do with the audience value for the app but in the Okta authentication API documentation, it claims that value is no longer in use so now I’m unsure where to go from here.

How do I authenticate to a native app with one of the Okta scopes?
