Can't add co-author: NOMAD beta version

Dear Admin,
Can’t find option to add co-author in the metadata NOMAD beta version. No option for sharing as well. Any help?

Thank you for your question Badal,

we added a project-style user management that gives other users edit and view rights (and makes them co-authors and reviewers respectively). There is a button showing an icon with two people on the top-right of each upload page. This button will allow to manage the co-authors and reviewers for an upload.

There is also this tutorial video on the new upload system: FAIRmat tutorials 1: Publishing data with NOMAD - YouTube
