When sharing topics and clusters created in Collabwriting with external collaboratores, you have the option to set Access Roles.
This gives you more control over who, how and when can interact with the insights you choose to keep.
Currently, supported roles are:
Viewer - Can view snippets and comments for shared topics/clusters
Commenter - Can leave comments and reactions on snippets
Editor - Can add and remove snippets from a shared topic/cluster
While Clusters and Topics in the Team Version are by default shared with all members of the team, access to some information can be limited by adding a private cluster.
