Permission Matrix Setup and Usage
This is one of the most crucial functionalities that helps the organizer control the connections between the various visitor and exhibitor categories.
The organiser can set a permission matrix to make any category users visible to other categories. It also helps in enabling the meet and message option wherein specific user categories are allowed to send meet and message requests to other categories.
The Permission Matrix can be set by enabling the toggles for each user category
In the image below, the x-axes are the Receiver category and Y-axes are the Initiator category.
