It looks like you can't use it at all, to be honest.
You may not: ... (v) represent that output from the Services was human-generated when it is not;...
Given that Springer (from the link in your question) says you can't credit ChatGPT as an author and OpenAI says you have to be up front that the text was generated by ChatGPT, I'd say you're going to have a hard time getting both requirements together.
The link to the ACL that Franck Dernoncourt posted puts a lot of requirements on the use of ChatGPT for an ACL conference. Basically, the ACL page says "Don't use it. If you must use it, consider all these requirements and how you will make sure they are met before you try to convince us that your use of ChatGPT is merited."
The ACL site mentions some cases where it is OK to use text tools - but it does not put ChatGPT in that category. It also mentions all the ethical and legal doubts surrounding the use of ChatGPT.
Why bother with ChatGPT? You'll have to go through any number of iterations before it tosses out something you like, edit its output, clean it up, and check it for plagiarism (there's always the chance that it'll reconstitute some exact piece of text from the stuff it analyzed.)
Using ChatGPT will simply be more work for a questionable gain. Write your text yourself. Then you can be sure that the text says what you meant and that it won't accidentally plagiarise someone else's text.
