@nickfloyd - not sure the proper way to request a CR from the maintainers on this one to make sure I'm not going off the deep end.

Was hoping I followed the structure of other modules + the 2 endpoints added before my change.

Hety @DanBradbury Thank you for the changes here ❤️. We do our best to try to get things like this reviewed quickly in light of our process. We're a small team of two responsible for about 80 repos so things can get backed up a bit. Apologies for the delay.

Great work here, would you mind addressing the linting issues? Then I'd be glad to get this out the door!

Thank you for the CR! @nickfloyd

I've fixed the remaining rubocop issues and pushed it up
