Provide example how to retrieve and update public/private/unsafe metadata

[d-stoll]

Hi Clerk-Team,

nice to see that you are working on a Java SDK for the clerk backend! Really eager to replace our internal clerk library with this project.

However, I encountered the following issue:

When retrieving the details of a user, the public metadata (as well as unsafe and private metadata) just returns an object of an empty wrapper class. Do I have to subclass or parse the metadata somehow to get a usable object?

Here is an example:

package hello.world;

import com.clerk.backend_api.Clerk;
import com.clerk.backend_api.models.operations.GetUserResponse;
import java.lang.Exception;

public class Application {

    public static void main(String[] args) throws Exception {
        try {
            Clerk sdk = Clerk.builder()
                .bearerAuth("<YOUR_BEARER_TOKEN_HERE>")
                .build();

            GetUserResponse res = sdk.users().get()
                .userId("<value>")
                .call();

            if (res.user().isPresent()) {
                var user = res.user().get();
                
                if (user.publicMetadata().isPresent()) {
                  // This is just an empty object with no methods
                   var publicMetadata = user.publicMetadata().get();

                   // What do I have to do here to get the actual metadata?
                }
            }
        } catch (Exception e) {
            throw e;
        }
    }
}
