How to Prevent From Accidentally closing Laravel Nova Resource?

To prevent accidentally closing the Laravel Nova resources page during creating or editing content, you have to set the "preventFormAbandonment" properties to true. By doing so, when any misclick that may lead to closing the page will be prevented and a confirmation form will be displayed.

/**
 * Indicates whether Nova should prevent the user from leaving an unsaved form, losing their data.
 *
 * @var bool
 */
public static $preventFormAbandonment = true;
