Deleting an item is a common action in many applications, but it is important to ensure that the user confirms their intention before proceeding with the deletion. One common way to achieve this is by using a confirmation popup.

To implement this feature, you can start by adding a button or link that triggers the delete action. When the user clicks on this button or link, a confirmation popup should be displayed. This popup should ask the user if they really want to delete the item and provide them with two options: "yes" and "no".

If the user clicks "yes", the application should proceed with the deletion of the item. If the user clicks "no", the application should do nothing and close the popup.

The confirmation popup can be designed in various ways, depending on the application's design and user experience. However, it should always be clear and easy to understand, so that the user can make an informed decision about whether to proceed with the deletion or not.

In this application we can delete with confirm popup and there is delete all button that delete all data with the PIN 1234 and black and white UI.
