Dataverse server and BinderHub

I am trying to setup Binder with a Dataverse server that is used within my structure :

So far Binder tells me it cannot find the repository when I try to request it with a Dataverse Pid from this server.

The BinderHub docs are not very clear on this and I cannot find exemple of not harvard dataverse application.

Do I have to setup a new repository provider or is it possible to specify the right URL with configuration files ?
