Is this functionality already implemented?

I see this has been implemented in the codebase as ConfirmationDialog and useConfirm hook

https://github.com/podkrepi-bg/frontend/blob/master/src/components/common/ConfirmationDialog.tsx

https://github.com/podkrepi-bg/frontend/blob/master/src/common/hooks/useConfirm.ts

What might be left is to use these components in the delete modals and replace the ModalStore implementations
