A Navigation icon you create will not display unless you have selected what for that icon?

For a Navigation icon to be displayed in the Cvent Mobile Event App, it is essential to select an image for that icon. The image serves as the visual representation of the navigation element, allowing users to easily identify it within the app's interface. Without an image, the app has no graphical element to present, which means the icon would not be visible to the users, rendering it ineffective for navigation purposes.

While labels, color schemes, and priority levels can enhance the overall appearance and functionality of the navigation elements, they do not fulfill the requirement for the icon's visual display. The image is the fundamental component that ensures the navigation icon is not only present but also instantly recognizable to the users, facilitating a smoother and more intuitive user experience.
