Q: how can I move a message on my Iphone when pressing trash button

As described in the article, when I delete a gmail email on my Iphone, it gets archived instead. I wanted to change that, but when I follow the descriptions in this article, my screen looks different and I can't get to the option "Archive Messages". Instead, in the folder: Mail, Contacts, Calendars > I can't find--> Gmail Account

I can only get into the settings of my gmail account, but there I can set things lik "Mail Days to Sync" and "Mail Folders to push" but nothing about archiving ...

Can anyone help??
