If you have been invited to collaborate on a team project, you receive an invitation notification in the Creative Cloud desktop application. There are two ways you can choose to accept or reject an invitation.
When you are working on a Team Project, you can learn which other collaborators are working on the same Team Project at the same time. You can view the list of collaborators and their online or offline status in the collaborators control. Also, you can view which collaborator has shared changes for an asset and identify the collaborator that has conflicts with your project.
If the collaborators are online, then their profile pictures appear in the collaborators control. You can click the pop-up screen to view the list of online and offline collaborators.
When you click the asset status badge, a notification pop-up message appears whenever your collaborator edits a shared asset or shares an edited asset.
