Is my coworker using ChatGPT?

My coworker sent me this text, looks suspiciously AI generated, can someone confirm?

This is only some sections of her message:

Happy holidays, and thanks for laying out your ideas so clearly! Even without our face‑to‑face meeting, you’ve kept the momentum rolling!
I’m completely on board. Let’s build a concise info sheet and email it to area teachers. Reaching middle‑schoolers earlier is a smart move. Especially offering guest‑performer invitations as low‑pressure way for them to dip a toe in.
Your leadership this season has been outstanding. New leadership will give others a chance to shine—just as you’ve suggested. We’ll announce the opening at the meeting and start lining up candidates; meanwhile, I’d love for you to stay involved. What role(s) do you think you would like to undertake?
