Salesforce SDK collaborate() issue

I am having issues getting the SDK to add a Group collaborator to my Folder. I am able to create a folder template structure using the BoxToolkit. From the documentation and my tests, I am unable to use the boxToolkit.createCollaboration() method as that it seems to only support the addition of User records, which is why I using the SDK.

The code I am trying to execute is:

BoxApiConnection api = new BoxApiConnection('');
BoxCollaborator user = new BoxGroup(api, '');
BoxFolder folder = new BoxFolder(api, '');
folder.collaborate(user, BoxCollaboration.Role.EDITOR);

VARIABLE_ASSIGNMENT [128]|response|"System.HttpResponse[Status=Unauthorized, StatusCode=401]"|0x61ebcbba

I scoured the developer portal configuration for My App, but couldnt find anything. I tried the Application Scope to give Enterprise properties, Groups but that didnt seem to work either.

Any help on what i might be doing wrong would be great! Thanks!
