Is there any example of rego files where this package can be used?

Apologies for the very late reply.

There is an old Styra OSS repo for a demo application called "TicketHub" that has some usage examples for the various OPA SDKs, including this one. Hopefully that can help you get started if you're using ASP.NET Core.
