Honestly, out of the box it doesn't. Restic is CLI only, there's no built-in "click to restore" flow. For a non-tech person you'd need two things ready ahead of time: the repo password and access keys stored somewhere they can actually find (password manager, printed sheet, whatever works), and a GUI tool, because asking them to run terminal commands isn't realistic.

emuell/restic-browser on GitHub is a decent option, cross-platform, lets you browse snapshots and restore files without touching a CLI, though it still needs restic installed on the machine and the repo credentials to unlock anything.

Or use an AI to help with restore. Should work as long as you have the passwords and keys secured and ready to use.
