Yes. As the dataset creator, you are the sole ‘owner’ of the dataset. But you can invite your colleagues, co-authors or student assistants to the preparation process at the pre-publication stage. At this preparation stage, datasets are only visible to you and to those people you give access to. Via "Collaboration", you can add users via a search box or invite via an invitation link (as the invitation link is not yet available, they have to register first in order that you can grant access). You can grant view, edit or admin rights and also revoke access to your dataset.
