Add Co-Publisher or Co-Editor

The types of collaborators and their permissions are as follows:

Co-Editors - can edit the entry's details and metadata, trim media, replace media, edit captions, edit chapters and edit slides. Co-editors cannot delete media or add new co-editors and co-publishers. Co-editors can see the analytics page for the media they co-edit.
Co-Publishers - can publish media to their entitled Categories or Channels. This option must be enabled by your KMS administrator for this tab to display. Group support may be enabled for the Media Collaboration features. When enabled, you can select groups that may be assigned as co-editors/publishers for an entry.
Co-Viewers - are only able to view media and do not have editing permissions, nor are they allowed to view unlisted entries, unless they are also co-publishers or co-editors of that entry.
