Conditional visibility of a container

Hello..!!

My app facilitates the creation, viewing, and deletion of appointments. I aim to display a default message—"No appointments found. Please begin by tapping the + icon..."—whenever there are no existing appointments for the user. While the current visibility feature can show or hide elements based on a boolean flag from the API response, it doesn't automatically conceal the container with the default message when the API returns an empty dataset (zero rows)
