An example with a ResourceOperation is given here. Is there any specific thing you had an mind?

[deanbrindley87]

ah nice one, thanks. not yet no, i just couldn't find it as it was bundled in with the regular JSON example.

going to start integrating these operations into our project so might have a few questions at some point - happy to close! 👍

sounds good! the fact that you raised this may mean that we should extract this example into another separate file so it can be more visible
