Sad news: it can’t be done…
Your best path: netinstall it with same version and restore the backup.
If you have the export of configuration, you could netinstall with latest version and reapply configuration.

If you added it on Dude with correct password you can select the device, copy with CTRL+C and then if you paste in a txt you’ll see the XML of the device with the password.
