Automatic reply Email: out of office setting missing!

Hi, I’m trying to set up an automatic reply, out of office email in my Mail app, iOS 18.2, iPhone 16 pro.

i don’t have the ‘automatic reply’ button that people point to in tutorials.

settings-apps-mail-mail accounts-choose account-“automatic reply”

I have also tried to find “passwords and accounts” as another option but don’t have thins setting as I have the new “passwords app”.

ive reset my phone but can’t find any way to set up out of office auto replies for email. Any help please?

(image shows sections where “automatic reply” is listed in tutorial online but missing here)
