No, only the Owner can present a Diggle in Personal Workspace.
However, all collaborators can still edit a Diggle while used by the Owner in a live session.
For example, two of you are doing a training session and have
collaborated on content development. During a live training session, both of you can go in and
make changes if necessary to help each other out!
Note: This is only for Personal Workspace.
In a Company Workspace, everyone can present simultaneously.
