In a SuiteBox meeting, one user will always be in Control. The user with Control is able to import or delete .pdf documents and images, hide or show documents, scroll through and sign documents, or screen share. The user without control will receive the shared documents, see the document scroll, and see signatures being placed, and observe the screen being shared.
The host of the meeting is able to determine who currently has Control by clicking the 'Give Control/Take Control' button. This ensures both users see the exact same thing, at the same time, like you would expect in a face-to-face meeting.
Please note: If you want your participant to sign, you will need to pass Control to them.
