FWIW, I'm a native English speaker and I've used ChatGPT to copy edit my own text to good effect, as well as both summarising and expanding on topics. If it helps you, I hope you don't feel the need to avoid using a useful tool.
If it's causing issues, you can remove mentions of it (I know there's also a desire to call out when it's not your own words entirely though). I'd only feel the need to explicitly say it was from a model if I'd not reviewed it - to make sure if it said something wrong it was clear to readers I'd not approved it.
I'd like it if it was more accepted though and it's a shame this has come up as a discussion.
