Clear storage.local outside of WebExtension

Question

How to clear storage.local outside the WebExtension code without uninstalling the WebExtension?

Inside the WebExtension, storage.local.clear() could be used. On uninstall, storage.local is cleared as well.

Is there another way to remove either the WebExtension's storage.local or all of it? (Either in the browser console, the command line or ...?)
