Your message effectively requests additional work but can be polished for clarity and tone. Here's a refined version:

@RobQuistNL, thank you for your PR! 👍

Could you please add tests for your changes? This will aid in future maintenance and ensure that no regressions occur.

[bednar]

Thanks again for your PR 👍. Everything looks good, can you just satisfy our checklist (CLA and update CHANGELOG.md)?

[RobQuistNL]

Thanks @bednar :)

I think I did all those things. Maybe best to add these requirements into the Contributing section or in a CONTRIBUTING.md file so in the future people spot it easier up front.

Thanks for reviewing so promptly!

LGTM 🚀
