What not to paste
Treat the chat box like an email to a stranger.
Depending on the tool and plan, what you paste may be stored or reviewed by the provider. Check the data settings, and when in doubt leave it out or anonymise it.
Keep out: customer lists with names and emails, passwords and keys, unreleased material under embargo, contracts under NDA. Anonymise by swapping names for labels ("Client A", "Customer 14") and keeping the key on your side. An approved company tool may widen what is allowed, but the policy decides, and you still check the output.

Learn it in the course, copy it from a playbook, see it work in a case study.
