In other versions of Nintex Forms it was possible to customize a content type's form by going the Content Type Settings > Eddit Form with Nintex forms but I don't see that option on the O365 version. I have added the App "Nintex Forms for O365, am I missing anything else?
Note that this is not a list based form, it is just a content type.

Once you start customizing the Form in a list/ library where you have multiple content types, Nintex will ask you which content type you would actually like to customize.
