After you send a session collaboration invitation, the Session Collaboration user interface turns into a dashboard that shows the current state of the shared remote desktop session (collaborative session) and enables you to take certain actions.

A Horizon administrator can prevent the hand off of control to a session collaborator. For Windows remote desktops, see the Allow control passing to collaborators group policy setting in the Configuring Remote Desktop Features in Horizon document. For Linux remote desktops, see the collaboration.enableControlPassing parameter in the Setting Up Linux Desktops in Horizon document.
