It would be helpful to have a way to control which users are able to initiate and resolve a claim return. Some libraries will only want certain levels of staff to be able to initiate the Claim Return, and likewise, only certain staff should be able to resolve it. Perhaps a permission for each of those functions?

I would add that using a permission to show/hide the button would be useful and may be the easiest way to limit certain staff.
As it's not also used with item bundles, we might need to take that into account.
