Not sure if this was really mentionned, but using one reusable element with 3 text states (ID, DB and if you want, Title to show something like Are you sure you want to delete “this thing title”?)

And using API Connector + Data API “DELETE” request with url like
https://myapp.bubbleapps.io/api/1.1/obj/[DB]/[ID]

So you set states > show reusable element (popup)
If user select yes > API connector DELETE action > hide popup

However, it must cost more WU using this option.
