Hide Page publish and unpublish options in AEM Cloud

Hello All,

We have created a Content Author user group from Admin Console in cloud and assigned some User profiles to that group. I can see that group in AEM test instance but not sure how to hide Page Publish and Page Unpublish options from page properties for this group. I tried disallow rep:write permission for /content/project-name path but still its showing publish options. Any ideas on how to hide this options?
