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 7 document. For Linux remote desktops, see the collaboration.enableControlPassing parameter in the Setting Up Horizon 7 for Linux Desktops document.
Prerequisites
Start a collaborative session. See Invite a User to Join a Remote Desktop Session.
