This feature permits an owner to set the board to "kick" and remove users or navigate users to the home screen after a certain amount of minutes of inactivity. This is useful when you want a kiosk to return to a starting position when users walk away. This is also helpful with guests that may have forgotten to close the board at the end of a session.
To access this setting, go to the "Board Settings" under the User Dropdown in the top right, then under Customization scroll to the choice, determine how many minutes and whether to "kick" or navigate users home, and make sure it is selected to be active.
