dcc_confirmdialog

dcc_confirmdialog is used to display the browser’s native
“confirm” modal, with an optional message and two buttons (“OK” and “Cancel”).
This ConfirmDialog can be used in conjunction with buttons when the user is
performing an action that should require an extra step of verification.

See dcc_confirmdialogprovider
for an easier way to display an alert when clicking on an item.
