As a canvas analyst, you can create alerts in two ways:
From the Floating Object Controls: Select the cell, visual, or frame you want to create an alert for. The floating controls that appear will include an option to Add alert. Click this button to configure your new alert.
From the Alerts Sidebar: On the right side of your Count canvas, you'll find the Alerts sidebar. Click the + Add alert button at the top to create a new alert and then select the desired cell, visual, frame, or report.
Once created, all alerts for the current canvas will be listed in the Alerts sidebar for easy management.
