Without doing anything, the form permissions can be defined to limit by role. So even if someone sees a button, it doesn't mean they can interact with the form. If you don't like the visual, you'll have to incorporate custom code or a plugin. If you go the plugin route, try members -> https://members-plugin.com/docs/shortcodes/

With the plugin you can wrap content up in a shortcode and limit it's visibility based on role among other things. Something like:

[members_access role="editor"]Hide this content from everyone but editors.[/members_access]
