That depends on the role a user has been created with and your account type.

E.g.

An owner of an account has the highest level of access. Only they can access and manage billing matters; add more licenses; assign admin privileges; view and download invoices; and upgrade, downgrade, or cancel a subscription.

An admin can access all features and functionality, except for permissions reserved for the owner. They can invite and remove members from the team (based on the number of licenses set by the owner), set user roles; create and edit workspace groups; change the team’s name and logo, and access any Kahoot in the shared workspace.

A member (The default role) can access every section of the platform, but they cannot extend invitations or purchase licenses. They can edit workspace groups; host, assign, and edit any Kahoot in the shared workspace; and view advanced visual reports.

A limited member does not have access to all the shared workspace's Kahoots or shared space. They can be invited to workspace groups and have their own folder within the shared space. 

All roles can host, assign, and edit any Kahoot in the shared workspace, depending of the license type of course.
