Missing tests

[digitall-it]

It would be nice if this package had some tests and start listing which ones may be in the scope. For example, testing features of the underlying Spatie package or Filament features could be meaningless. Instead, things like checking if the field translations are respected, or if the restoration feature actually does the job, may be interesting test cases worth looking after.

Definitely interesting, but I currently don't have the time to implement this myself. I'd be happy to accept a good PR though.
